Some models feature a shutdown mode to conserve power in battery-powered systems. Some require no external components. All, except one model, feature a built-in charge pump voltage converter, allowing them to operate from a single +5V power supply. All drivers and receivers meet all EIA RS-232D and CCITT V.28 requirements. The Series is available in plastic and ceramic DIP and SOIC packages.SELECTION TABLEABSOLUTE MAXIMUM RATINGS This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied.

The SP230A, SP235A/B, SP236A/B, SP240A/B, and SP241A/B feature ashutdown mode which reduces device power dissipa-tion to less than 5µW. All feature low power CMOS operation, which is particularly beneficial in battery-powered systems. The SP235A/B use no external components and are ideally suited where printed circuit board space is limited.All products in the Series, except the S P239A, includetwo charge pump voltage converters which allowthem to operate from a single +5V supply. These converters convert the +5V input power to the ±10V needed to generate the RS-232 output levels. The SP239A is designed to operate from +5V and +12V supplies. An internal charge pump converter produces the necessary –12V supply. All drivers and receivers meet all EIA RS-232D and CCITT V.28 specifications.The Series are available for use over the commer-cial, industrial and military temperature ranges. They are packaged in plastic and ceramic DIP, and SOIC packages. For product processed and screened to MIL–M–38510 and MIL–STD–883C requirements, please consult the factory.THEORY OF OPERATIONThe SP230A/B–241A/B series devices are made up of t hree b asic c ircuit b locks –1) t ransmitter, 2) r eceiver and 3) charge pump. Each model within the series incorporates variations of these circuits to achieve the desired configuration and performance.Driver/TransmitterThe drivers are inverting transmitters, which accept TTL or CMOS inputs and output the RS-232 signals with an inverted sense relative to the input logic levels. Typically the RS-232 output voltage swing is ±9V. Even under worst-case loading conditions of 3kΩ and 2500pF, the output is guaranteed to be ±5V, which is consistent with the RS-232 standard specifications. The transmitter outputs are protected against infi-nite short-circuits to ground without degradation in reliability.The drivers of the SP230A, SP235A/B, SP236A/B, SP240A/B and SP241A/B can be tri-stated by using the SHUTDOWN function. In this “power-off” state, the output impedance will remain greater than 300 Ohms, again satisfying the RS-232 specifications. Should the input of the driver be left open, an internal 400kΩ pull–up resistor to VCCforces the input high, thus committing the output to a low state.The slew rate of the transmitter output is internally limited to a maximum of 30V/µs in order to meet theTable 1. EIA Standards DefinitionCharge Pump Output Loading versus VCC; a) V+; b) V–ENABLE Input (EN)The SP235A/B , SP236A/B , SP239A, SP240A/B, and SP241A/B all feature an enable input (EN), which allows the receiver outputs to be either tri–stated or enabled. The enable input is receiver outputs. This can be especially useful when the receiver is tied directly to a micropro-cessor data bus.Protection From Shorts to >±15VThe driver outputs are protected against shorts to ground, other driver outputs, and V + or V -.For protection against voltages exceeding ±15V,two back–to–back zener diodes connected to clamp the outputs to an acceptable voltage level are recommended. (Refer to Figure 3.)Improved Drive Capability for Mouse ApplicationsEach of the devices in this data sheet have improved drive capability for non-standard ap-plications. Although the EIA RS-232D stan-dards specify the maximum loading to be 3k Ωand 2500pF, the SP230A , SP234A , SP235A/B ,SP236A/B , SP237A , SP238A , SP239, SP240A/B, and SP241A/B can typically drive loads as low as 1k Ω and still maintain ±5V outputs. This feature is especially useful when the serial port is intended to be used for a “self-powered”mouse. In this case the voltage necessary to operate the circuits in the mouse can be derived from the RS-232 driver output as long as the loading is ≥1k Ω (refer to Figure 4). For applica-tions which even exceed this requirement, driv-ers can be connected in parallel, increasing the drive capability to 750Ω, while maintaining the ±5V V OH and V OL levels (refer to Figure 5).Figure 3. High Voltage Short Circuit ProtectionFigure 2. Charge Pump Voltage Inverter output impedance of V + and V -, which will degrade V OH and V OL . Capacitor values can be as low as 1.0µF.Shutdown (SD)The SP230A , SP235A/B , SP236A/B ,SP240A/B and SP241A/B all feature a control input which will disable the part and reduce V CC current typically to less than 5µA, which is especially useful to designers of battery–pow-ered systems. In the “power–off” mode the receiver and transmitter will both be tri-stated.V + will discharge to V CC , and V - will discharge to ground.For complete shutdown to occur and the 10µA current drain to be realized, the following con-ditions must be met:• +5.00V must be applied to the SD pin;• ENABLE must either 0V, +5.0V or not connected;• the transmitter inputs must be either +5.0V or not connected;• V CC must be +5V;• Receiver inputs must be >0V and <+5VPlease note that for proper operation, the SD input pin must never be left floating.Table 2.

Parallel DriversWake-Up FeatureThe SP235B , SP236B , SP240B and SP241B have a wake-up feature that keeps all receivers in an enabled state when the device is in the shutdown mode. Table 2 defines the truth table for the wake-up function. Timing for the wake-up function is shown in Figure 6.If the SP235B , SP236B , SP240B and SP241B are powered up in the shutdown state (SD driven high during V CC power up), the part must remain in a powered on state for a minimum of 3ms before the wake-up function can be used. After the 3ms wait time, there is a 2ms delay time before data is valid for both enable and disableFigure 6. Wake–Up and Shutdown Timingof the charge pump. If the SP2XXB is powered up with SD low, then only the 2ms delay time will apply (refer to Figure 6). Under normal operation, both the wait time and delay time should be transparent to the user.With only the receivers activated, the device typically draws less than 5µA (10µA max) sup-ply current. In the case of a modem interfaced to a computer in power-down mode, the RI (ring indicator) signal from the modem would be used to “wake up” the computer, allowing it to accept the data transmission.After the ring indicator signal has propagated through the SP2XXB receiver, it can be used to trigger the power management circuitry of the computer to power up the microprocessor and bring the SD pin to the SP2XXB low, taking it out of shutdown. The receiver propagation de-lay is typically 1µs. The enable time for V+ and V- is typically 2ms. After V+ and V- have settled to their final values, a signal can be sent back to the modem on the DTR (Data Terminal Ready) pin signifying that the computer is ready to accept and transmit data.All receivers that are active during shutdown maintain 500mV (typ.) of hysteresis.Varying Capacitor ValuesAs stated earlier, the capacitor values are some-what non-critical. Since they are an actual compo-nent of the charge pump circuitry, their value will affect its performance, which in turn affects the V OH and V OL levels. There is no upper limit for the value of any of the four capacitors; lower values will impact performance. C 1 and C 2 are respon-sible for the charge accumulation and can be reduced to 1µF; this will increase the output im-pedance of V + and V –. Reducing these capacitor values will limit the ability of the SP2XXA/B to maintain the dc voltages needed to generate the RS-232 output levels. Capacitors C 3 and C 4 can also be reduced to 1µF; doing so will increase the ripple on V + and V–.Typically each driver will require 1µF of capaci-tance as a minimum to operate within all specified parameters; if five drivers are active in the circuit,then C 3 and C 4 should be 5µF. In order to operateat these minimum values, the supply voltage must be maintained at +5.0V ±5%. Also, the ambient operating temperature must be less than 60°C.The capacitor values must be chosen to suit the particular application. The designer must bal-ance board space, cost and performance to maxi-mize the design. The capacitors can be polarized or non–polarized, axial-leaded or surface-mount.As the size and value decrease, so does the cost;however, the value should be chosen to accom-modate worst-case load conditions.IBM Modem Port InterconnectionsINTERFACE EXAMPLE – A MODEM ON THE IBM PC SERIAL PORTThe RS-232 standard defines 22 serial interface signals. These signals consist of ground lines,timing, data, control and test signals, plus a set of signals rarely used for a second data channel.Many of these signal lines are not used in typical RS-232 applications; in fact, the IBM ® PC serial port is implemented using only nine pins.For example, consider the case of a PC using this nine pin port to communicate with a peripheral device such as a modem. We see the following activity on each of the RS-232 lines as the computer and modem are activated and commu-nicate with each other as well as the remote modem at the other end of the phone line.Signal Ground (GND)The Signal Ground pin acts as a reference for all the other signals. This pin is simply maintained at a 0V level to serve as a level to which all other signals are referenced. Both the PC and the modem will have this line connected to their respective internal ground lines.Data Terminal Ready (DTR)This is the pin the computer uses to tell periph-eral devices that it is on–line and ready to communicate.Data Set Ready (DSR)Peripheral devices use this line to tell the com-puter that they are on–line and ready to commu-nicate. When the modem is turned on and has completed its self–test routine (assuming it does one), it will send a signal to the PC by asserting this line.Request To Send (RTS)The computer activates this line to notify the peripheral device that it is ready to send data. In this example, the computer notifies the modem that it is ready to send data to be transmitted by the modem.Clear To Send (CTS)This is the line on which the peripheral device tells the computer that it is ready to receive data from the computer. If the modem was not ready, i.e. it was performing a loop–back self–test, for example, it would not assert this line. Once the modem was ready to receive data from the PC, it would assert this line. When it receives the CTS signal from the modem, the PC knows that a data transmission path has been established between itself and the modem.Transmitted Data (TD or TX)This is the pin on which the computer sends the actual data signal to be transmitted, i.e. a posi-tive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (–3V to –15V) to represent a logic “1”. The PC would send the data on this line to be transmitted by the modem. Ring Indicator (RI)This line is used by the peripheral device to tell the computer that a remote device wants to start communicating. The modem would activate the RI line to tell the computer that the remote modem was calling, i.e. the phone is ringing. Data Carrier Detect (DCD)This line is used by the modem to tell the computer that it has completed a transmission path with the remote modem, and to expect to start receiving data at any time.Received Data (RD or RX)This is the pin on which the modem sends the computer the incoming data signal, i.e. a posi-tive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (-3V to -15V) to represent a logic “1”.INTERFACE EXAMPLE – A PRINTER ON THE IBM PC SERIAL PORTThe RS-232 standard defines 22 serial interface signals. These signals consist of ground lines, timing, data, control and test signals, plus a set of signals rarely used for a second data channel. Many of these signal lines are not used in typical RS-232 applications; in fact, the IBM® PC serial port is implemented using only nine pins.For example, consider the case of a PC using this nine pin port to communicate with a peripheral device such as a printer. We see the following activity on each of the RS-232 lines as the com-puter and printer are activated and communicate. Signal Ground (GND)The Signal Ground pin acts as a reference for all the other signals. This pin is simply maintained at a 0V level to serve as a level to which all other signals are referenced. Both the PC and the printer will have this line connected to their respective internal ground lines.Data Terminal Ready (DTR)This is the pin the computer uses to tell peripheral devices that it is on–line and ready to communi-IBM Printer Port Interconnectionscate. Once the computer is powered–up and ready, it will send out a signal on the DTR to inform the printer that it is powered–up and ready to go. The printer really doesn’t care, since it will simply print data as it is received. Accordingly, this pin is not needed at the printer.Data Set Ready (DSR)Peripheral devices use this line to tell the computer that they are on–line and ready to communicate. When the printer is turned on and has completed its self–test routine (assuming it does one), it will send a signal to the PC by asserting this line. Request To Send (RTS)The computer activates this line to notify the peripheral device that it is ready to send data. In this example, the computer notifies the printer that it is ready to send data to be printed by the printer. Clear To Send (CTS)This is the line on which the peripheral device tells the computer that it is ready to receive data from the computer. If the printer was not ready, i.e. it was out of paper, for example, it would not assert this line. Once the printer was ready to receive data from the PC, it would assert this line. When it receives the CTS signal from the printer, the PC knows that a data transmission path has been established between itself and the printer. Transmitted Data (TD or TX)This is the pin on which the computer sends the actual data signal representing the actual informa-tion to be printed, i.e. a positive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (-3V to -15V) to represent a logic “1”. Ring Indicator (RI)This line is used by the peripheral device to tell the computer that a remote device wants to start com-municating. A modem would activate the RI line to tell the computer that a remote modem was calling, i.e. the phone is ringing. In the case of a printer, this line is unused.Data Carrier Detect (DCD)This line is used by a peripheral device to tell the computer to expect to start receiving data at any time. Since the printer would not be sending data to the PC in this case this line is not needed.Received Data (RD or RX)This is the pin on which the computer receives the incoming data signal, i.e. a positive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (-3V to -15V) to represent a logic “1”. Again, in this instance, since the printer will not be sending the PC any data, this line is not needed.ORDERING INFORMATION

Production processing does not necessarily include testing of all parameters.Copyright © 1999-2005, Texas Instruments IncorporatedPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.All trademarks are the property of their respective owners.DESCRIPTIONThe OPA277 series precision op amps replace the industry standard OP-177. They offer improved noise, wider output voltage swing, and are twice as fast with half the quiescent current. Features include ultra low offset voltage and drift, low bias current, high common-mode rejection, and high power supply rejection. Single, dual, and quad versions have identical specifications for maximum design flexibility.OPA277 series op amps operate from ±2V to ±18V supplies with excellent performance. Unlike most op amps which are specified at only one supply voltage, the OPA277 series is specified for real-world applications; a single limit applies over the ±5V to ±15V supply range. High performance is maintained as the amplifiers swing to their specified limits. Because the initial offset voltage (±20µV max) is so low, user adjustment is usually not required. However, the single version (OPA277) provides exter-nal trim pins for special applications.OPA277 op amps are easy to use and free from phase inversion and overload problems found in some other op amps. They are stable in unity gain and provide excellent dynamic behavior over a wide range of load conditions. Dual and quad versions feature completely independent circuitry for lowest crosstalk and free-dom from interaction, even when overdriven or overloaded.Single (OPA277) and dual (OPA2277) versions are available in DIP-8, SO-8, and DFN-8 (4mm x 4mm) packages. The quad (OPA4277) comes in DIP-14 and SO-14 surface-mount pack-ages. All are fully specified from –40°C to +85°C and operate from –55°C to +125°C.FEATURESq ULTRA LOW OFFSET VOLTAGE: 10µV q ULTRA LOW DRIFT: ±0.1µV/°C q HIGH OPEN-LOOP GAIN: 134dBq HIGH COMMON-MODE REJECTION: 140dB q HIGH POWER SUPPLY REJECTION: 130dB q LOW BIAS CURRENT: 1nA maxq WIDE SUPPLY RANGE: ±2V to ±18Vq LOW QUIESCENT CURRENT: 800µA/amplifier q SINGLE, DUAL, AND QUAD VERSIONS q REPLACES OP-07, OP-77, OP-1771234567141312111098Out D –In D +In D V –+In C –In C Out COut A –In A +In A V++In B–In B Out BOPA427714-Pin DIP, SO-14ADBC12348765V+Out B –In B +In BOut A –In A +In A V –OPA22778-Pin DIP, SO-8ABAPPLICATIONSq TRANSDUCER AMPLIFIER q BRIDGE AMPLIFIERq TEMPERATURE MEASUREMENTS q STRAIN GAGE AMPLIFIER q PRECISION INTEGRATORq BATTERY POWERED INSTRUMENTS q TEST EQUIPMENT12348765Offset Trim V+Output NCOffset Trim–In +In V –OPA2778-Pin DIP, SO-8Offset Trim −In +In V −OPA277AIDRM(Connect to V −)Out A −In A+In AV −OPA2277AIDRM(Connect to V −)NC = No connection.OFFSET OFFSETVOLTAGE VOLTAGE DRIFT PRODUCT max, µV max, µV/°CPACKAGE-LEAD SingleOPA277PA ±50±1DIP-8OPA277P ±20±0.15DIP-8OPA277UA ±50±1SO-8 Surface Mount OPA277U±20±0.15SO-8 Surface Mount OPA277AIDRM ±100±1DFN-8 (4mm x 4mm)DualOPA2277PA ±50±1DIP-8OPA2277P ±25±0.25DIP-8OPA2277UA ±50±1SO-8 Surface Mount OPA2277U±25±0.25SO-8 Surface Mount OPA2277AIDRM ±100±1DFN-8 (4mm x 4mm)QuadOPA4277PA ±50±1DIP-14OPA4277UA±50±1SO-14 Surface MountNOTE: (1) For the most current package and ordering information, see the Package Option Addendum located at the end of this data sheet or visit the TI web site at .ABSOLUTE MAXIMUM RATINGS (1)Supply Voltage ....................................................................................36V Input Voltage .....................................................(V –) –0.7V to (V+) +0.7V Output Short-Circuit (2)..............................................................Continuous Operating Temperature ..................................................–55°C to +125°C Storage Temperature .....................................................–55°C to +125°C Junction Temperature......................................................................150°C Lead Temperature (soldering, 10s).................................................300°C ESD Rating (Human Body Model)..

vAPPLICATIONS INFORMATION The OPA277 series is unity-gain stable and free from unex-pected output phase reversal, making it easy to use in a wide range of applications. Applications with noisy or high imped-ance power supplies may require decoupling capacitors connecting a potentiometer as shown in Figure 1. This adjustment should be used only to null the offset of the op amp. This adjustment should not be used to compensate for offsets created elsewhere in a system since this can intro-duce additional temperature drift.FIGURE 2. Input Bias Current Cancellation.OPA277, OPA2277, OPA42779 SBOS079A FIGURE 3. Load Cell Amplifier.FIGURE 4. Thermocouple Low Offset, Low Drift Loop Measurement with Diode Cold Junction Compensation.DFN PACKAGEThe OPA277 series uses the 8-lead DFN (also known as SON), which is a QFN package with contacts on only two sides of the package bottom. This leadless, near-chip-scale package maximizes board space and enhances thermal and electrical characteristics through an exposed pad.DFN packages are physically small, have a smaller routing area, improved thermal performance, and improved electrical parasitics, with a pinout scheme that is consistent with other commonly-used packages, such as SO and MSOP. Addition-ally, the absence of external leads eliminates bent-lead issues.The DFN package can be easily mounted using standard printed circuit board (PCB) assembly techniques. See Appli-cation Note, QFN/SON PCB Attachment (SLUA271) and Application Report, Quad Flatpack No-Lead Logic Packages (SCBA017), both available for download at . The exposed leadframe die pad on the bottom of the package should be connected to V–.LAYOUT GUIDELINESThe leadframe die pad should be soldered to a thermal pad on the PCB. Mechanical drawings located at the end of this data sheet list the physical dimensions for the package and pad.Soldering the exposed pad significantly improves board-level reliability during temperature cycling, key push, package shear, and similar board-level tests. Even with applications that have low-power dissipation, the exposed pad must be soldered to the PCB to provide structural integrity and long-term reliability.Addendum-Page 1PACKAGING INFORMATIONOrderable Device Status(1)Package Type PackageDrawingPins Package QtyEco Plan(2)Lead/Ball FinishMSL Peak Temp(3)Samples (Requires Login)OPA2277AIDRMT ACTIVE VSON DRM 8250Green (RoHS & no Sb/Br)CU NIPDAU Level-1-260C-UNLIM OPA2277AIDRMTG4ACTIVE VSON DRM 8250Green (RoHS & no Sb/Br)CU NIPDAU Level-1-260C-UNLIM OPA2277P ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA2277PA ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA2277PAG4ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA2277PG4ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA2277U ACTIVE SOIC D 875Green (RoHS & no Sb/Br)Call TI Level-3-260C-168 HR OPA2277U/2K5ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)Call TI Level-3-260C-168 HR OPA2277U/2K5G4ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)Call TI Level-3-260C-168 HR OPA2277UA ACTIVE SOIC D 875Green (RoHS & no Sb/Br)Call TILevel-3-260C-168 HROPA2277UA/2K5ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA2277UA/2K5E4ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA2277UAE4ACTIVE SOIC D 875Green (RoHS & no Sb/Br)Call TI Level-3-260C-168 HR OPA2277UAG4ACTIVE SOIC D 875Green (RoHS & no Sb/Br)Call TI Level-3-260C-168 HR OPA2277UG4ACTIVE SOIC D 875Green (RoHS & no Sb/Br)Call TILevel-3-260C-168 HROPA277AIDRMR ACTIVE VSON DRM 83000Green (RoHS & no Sb/Br)CU NIPDAU Level-1-260C-UNLIM OPA277AIDRMRG4ACTIVEVSONDRM83000Green (RoHS & no Sb/Br)CU NIPDAU Level-1-260C-UNLIM芯天下--/Addendum-Page 2Orderable Device Status(1)Package Type PackageDrawingPins Package QtyEco Plan(2)Lead/Ball FinishMSL Peak Temp(3)Samples (Requires Login)OPA277AIDRMT ACTIVE VSON DRM 8250Green (RoHS & no Sb/Br)CU NIPDAU Level-1-260C-UNLIM OPA277AIDRMTG4ACTIVE VSON DRM 8250Green (RoHS & no Sb/Br)CU NIPDAU Level-1-260C-UNLIM OPA277P ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA277PA ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA277PAG4ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA277PG4ACTIVE PDIP P 850Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA277U ACTIVE SOIC D 875Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277U/2K5ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277U/2K5G4ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277UA ACTIVE SOIC D 875Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277UA/2K5ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277UA/2K5E4ACTIVE SOIC D 82500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277UAE4ACTIVE SOIC D 875Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277UAG4ACTIVE SOIC D 875Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA277UG4ACTIVE SOIC D 875Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA4277PA ACTIVE PDIP N 1425Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA4277PAG4ACTIVE PDIP N 1425Green (RoHS & no Sb/Br)CU NIPDAU N / A for Pkg Type OPA4277UAACTIVESOICD1450Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR芯天下--/Addendum-Page 3Orderable Device Status(1)Package Type PackageDrawingPins Package QtyEco Plan(2)Lead/Ball FinishMSL Peak Temp(3)Samples (Requires Login)OPA4277UA/2K5ACTIVE SOIC D 142500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA4277UA/2K5E4ACTIVE SOIC D 142500Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA4277UAE4ACTIVE SOIC D 1450Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR OPA4277UAG4ACTIVESOICD1450Green (RoHS & no Sb/Br)CU NIPDAU Level-3-260C-168 HR(1)The marketing status values are defined as follows:ACTIVE: Product device recommended for new designs.LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.NRND: Not recommended for new designs.

各种运放的个人意见和评价
各种运放的个人意见和评价首先玩音乐这是一门比较败家的行当啊！花费的金钱不计其数也不会去计较所花费了多少！这是共通点。
价钱贵不代表好声音.最重要自己中意！由于本人不是有钱人我买的都是拆机件。
虽然是会有“件损耗”但是胜在价钱便宜!我不是一个极度发烧友！只是喜欢享受而已！不过好的音乐对所有的人耳朵的讨好的来说总是不会拒绝吧!我在陶街见过的一个大叔玩的打磨音响他那发烧程度才叫疯狂呢！在过去一个多月抱着发烧的音色的追求。
在广州市的陶街买了不少高中低级数的运放和其他材料浪费了不少人民币！掉了不少脚毛!结果总结了一个道理音乐合适自己就好不要盲目地最求所谓的高品质自己够听就够了！太好了就会变的太盲目。
太纠结。
但是前提下好的运放需要好的声卡或者是好的功放机搭配出来的效果才华丽耐听！音色分为好多种！首先是自己对那音色的个人喜爱才有自己喜欢的运放风格！前提下所有的运放都是需要搭配顶级的材料芯片等才有好的效果出来的！市面上因为效果好的机子卖的价钱太过昂贵！才会出现大家所说的“打磨”出现！当然不想麻烦和对它要求不高的朋友就另当别论了。
入门级：ne5532:曾经被誉为的运放之王！声音温暖.有多个版本选择其中大S的5532an最好ti的5532P 最差！最基本的声音高音暗色.中频比较宽但肥.厚低频干而且实!声音略糙一点。
听过好的运放再听它就不想再用了！但是唯一的优势就是音乐味道很浓且价格便宜这样的经典比烂4558好太多了。
无什么要求的一粒大s解决问题！tl072，TL082D:来自久远历史的运放！高频明亮且有点失真！中频醇厚。
低频稍少音色一般对机子要求较高！三频分不清。
没有层次jrc2114：同tl82d差不多个人觉得效果比tl82还差点！醇厚圆润，但高频有衰减，没有明显的延伸，听起来有点不自然，而且2114最大的缺点是大动态混，正是这点让人感觉非常不爽。
音色不错有一点点点甜的味道。
低频少！三频乱！听耐了会觉得是噪音而不是音乐！jrc4580：和ne5532音色相差不大.个人认为效果一般不作详评！lm833n：开始听这个效果不错啊。

Power supply pins should be bypassed with 10nF ceramic capaci-tors.OPERATING VOLTAGEOPA237 series op amps operate from single (+2.7V to +36V) or dual (±1.35V to ±18V) supplies with excellent performance. Most behavior remains unchanged through-out the full operating voltage range. Parameters which vary significantly with operating voltage are shown in typical performance curves. Specifications are production tested with +2.7V, +5V, and ±15V supplies.OUTPUT CURRENT AND STABILITYOPA237 series op amps can drive large capacitive loads.However, under certain limited output conditions any op amp may become unstable. Figure 1 shows the region where the OPA237 has a potential for instability. These load conditions are rarely encountered, especially for single supply applications. For example, take the case when a+5V supply with a 10k Ω load to V S /2 is used. OPA237series op amps remain stable with capacitive loads up to 4,000pF, if sinking current and up to 10,000pF, if sourcing current. Furthermore, in single supply applications where the load is connected to ground, the op amp is only sourcing current, and as shown in Figure 1, can drive 10,000pF with output currents up to 1.5mA.FIGURE 1.

Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.Supply Voltage, V+ to V–.....................................................................36V Input Voltage.......................................................(V–) –0.7V to (V+) +0.7V Output Short-Circuit (1).......................................................................................Continuous Operating Temperature...................................................–40°C to +125°C Storage Temperature......................................................–55°C to +125°C Junction Temperature ....................................................................+150°C Lead Temperature (soldering, 10s)..................................................300°C NOTE: (1) Short circuit to ground, one amplifier per package.ABSOLUTE MAXIMUM RATINGSPACKAGE/ORDERING INFORMATION6®OPA237, 2237, 4237INPUT BIAS CURRENTvs INPUT COMMON-MODE VOLTAGE–12 –11–10 –9 –8 –7 –6I n p u t B i a s C u r r e n t (n A )Common-Mode Voltage (V)–15–10–5051015TYPICAL PERFORMANCE CURVESAt T A = +25°C and R L = 10k Ω, unless otherwise noted.POWER SUPPLY and COMMON-MODE REJECTIONvs FREQUENCY12010080 60 40 20 0P S R , C M R (d B )Frequency (Hz)101001k10k100k1M10MINPUT NOISE AND CURRENT NOISE SPECTRAL DENSITY vs FREQUENCY11k10010V o l t a g e N o i s e (n V /√H z )C u r r e n t N o i s e (f A /√H z )Frequency (Hz)101001k10k100kOPEN-LOOP GAIN/PHASE vs FREQUENCY1100 8060 40 20 0 –20V o l t a g e G a i n (d B )0 –45 –90 –135 –180P h a s e (°)Frequency (Hz)101001k10k100k1M10MCHANNEL SEPARATION vs FREQUENCYFrequency (Hz)C h a n n e l S e p a r a t i o n (d B )1301201101009080101001k 10k100kINPUT BIAS CURRENT vs TEMPERATURETemperature (°C)I n p u t B i a s C u r r e n t (n A )1412 10864–75–50–252550751001257OPA237, 2237, 4237®TYPICAL PERFORMANCE CURVES (CONT)At T A = +25°C and R L = 10k Ω, unless otherwise noted.OFFSET VOLTAGE DRIFT PRODUCTION DISTRIBUTIONP e r c e n t o f A m p l i f i e r s (%)Offset Voltage Drift (µV/°C)0.51.52.53.54.55.56.57.58.59.510.511.5302520 15 10 5 0OFFSET VOLTAGE DRIFT PRODUCTION DISTRIBUTION P e r c e n t o f A m p l i f i e r s (%)Offset Voltage Drift (µV/°C)16 1412 10 8 6 4 2 00.51.52133.52.544.555.566.5787.5OFFSET VOLTAGE DRIFT PRODUCTION DISTRIBUTIONP e r c e n t o f A m p l i f i e r s (%)Offset Voltage Drift (µV/°C)1210 8 6 4 2 00.51.52133.52.544.555.566.5787.5A, CMR, PSR vs TEMPERATURE Temperature (°C)A O L , C M R , P S R (dB )120 110100 90 80 70 60–75–50–250255075100125OFFSET VOLTAGEPRODUCTION DISTRIBUTIONP e r c e n t o f A m p l i f i e r s (%)Offset Voltage (µV)–750–650–550–450–350–250–150–50501502503504505506507512.510 7.552.50OFFSET VOLTAGEPRODUCTION DISTRIBUTIONP e r c e n t o f A m p l i f i e r s (%)Offset Voltage (µV)–950–850–750–650–550–450–350–250–150–50501502503504505506507508509509 87 6 5 4 3 2 1 0®OPA237, 2237, 423770605040302010101001k10kLoad Capacitance (pF)Overshoot(%)SMALL-SIGNAL OVERSHOOTvs LOAD CAPACITANCETYPICAL PERFORMANCE CURVES (CONT)At T A = +25°C and R L = 10kΩ, unless otherwise noted.LARGE-SIGNAL STEP RESPONSEG = 1, C L = 100pF, V S = +5V10µs/div1V/divSMALL-SIGNAL STEP RESPONSEG = 1, C L = 100pF, V S = +5V2mV/div1µs/divSMALL-SIGNAL STEP RESPONSEG = 1, C L = 220pF, V S = +5V2mV/div2µs/divOUTPUT VOLTAGE SWING vs OUTPUT CURRENT012345Output Current (mA)OutputVoltageSwing(V)SETTLING TIME vs GAINGain (V/V)SettlingTime(µs)100101–1–10–10089OPA237, 2237, 4237®TYPICAL PERFORMANCE CURVES (CONT)At T A = +25°C and R L = 10k Ω, unless otherwise noted.MAXIMUM OUTPUT VOLTAGEvs FREQUENCY1M100kFrequency (Hz)1k10k30 2520 15 10 5 0O u t p u t V o l t a g e (V p -p )QUIESCENT CURRENT vs TEMPERATURETemperature (°C)Q u i e s c e n t C u r r e n t (µA )30025020015010050–75–50–25255075100125SHORT-CIRCUIT CURRENT vs TEMPERATURETemperature (°C)S h o r t -C i r c u i t C u r r e n t (m A )12 10 8 6 4 2 0–75–50–252550SC _SC+7510012510®OPA237, 2237, 4237APPLICATIONS INFORMATIONOPA237 series op amps are unity-gain stable and suitable for a wide range of general-purpose applications. Power supply pins should be bypassed with 10nF ceramic capaci-tors.OPERATING VOLTAGEOPA237 series op amps operate from single (+2.7V to +36V) or dual (±1.35V to ±18V) supplies with excellent performance. Most behavior remains unchanged through-out the full operating voltage range. Parameters which vary significantly with operating voltage are shown in typical performance curves. Specifications are production tested with +2.7V, +5V, and ±15V supplies.OUTPUT CURRENT AND STABILITYOPA237 series op amps can drive large capacitive loads.However, under certain limited output conditions any op amp may become unstable. Figure 1 shows the region where the OPA237 has a potential for instability. These load conditions are rarely encountered, especially for single supply applications. For example, take the case when a+5V supply with a 10k Ω load to V S /2 is used. OPA237series op amps remain stable with capacitive loads up to 4,000pF, if sinking current and up to 10,000pF, if sourcing current. Furthermore, in single supply applications where the load is connected to ground, the op amp is only sourcing current, and as shown in Figure 1, can drive 10,000pF with output currents up to 1.5mA.FIGURE 1. Stability-Capacitive Load vs Output Current.FIGURE 2. Low and High-Side Battery Current Sensing.。

CSC-237A 数字式电动机综合保护测控装置说明书
CSC 237A数字式电动机综合保护测控装置1装置简介本装置适用于10kV及以下各种中性点非直接接地系统，作为大中型异步电动机(数百千瓦以上) 相间故障、过负荷、堵转等综合保护。
可在开关柜就地安装。
2 主要功能及技术参能2.1 保护功能⏹反应相间故障的速断保护⏹反应堵转的过电流保护⏹过负荷保护(可选择跳闸或仅告警发信)⏹长起动保护⏹过热保护（过热跳闸、过热告警、热积累记忆功能）⏹不平衡保护（断相/反相，负序过流保护，可选择定时限或反时限）⏹接地保护（零序过流保护，可选择跳闸或仅告警发信）⏹低电压保护⏹F-C过流闭锁⏹非电量保护2.2 测控功能⏹15路开入遥信采集、装置遥信变位、事故遥信⏹正常断路器遥控分合⏹Ua、Ub、Uc、Ia、Ic、P、Q、COSф等模拟量的遥测⏹各种事件SOE等2.3 技术参数3 保护元件3.1 长起动保护装置测量电动机起动时间Tstart的方法：当电动机的最大相电流从零突变到10%Ie时开始计时，直到起动电流过峰值后下降到120%Ie时为止，之间的历时称为Tstart。
（Ie为电动机额定电流。
）电动机起动时间过长会造成转子过热，当装置实际测量的起动时间超过整定的允许起动时间Tstart时，保护动作于跳闸。
图1 异步电动机起动电流特性为了降低起动电流，减少对电网的无功冲击，大型的异步电动机常常串联电抗器或者电阻，以实现降压起动；起动完毕后短接串联电抗器或者电阻。
本装置设置了专用的控制字，如果选择“降压起动方式投入”，则装置在起动完毕以后，给出一付“投全压”的接点，以便及时短接分压电抗器，使电动机进入额定电压运行。
为了试验方便，当CSC 237保护装置检测到电动机在“起动过程中”时（即上图中的Tstart时段），面板MMI最下一指示绿灯（备用）点亮。
3.2 过热保护过热保护综合考虑了电动机正序、负序电流所产生的热效应，为电动机各种过负荷引起的过热提供保护，也作为电动机短路、起动时间过长、堵转等的后备。
各种常见运放的特色图解
各种常见运放的特色图解初谈各种运放的特色NE5532NE5532：确实有点胆味，解析力一般，高频比较燥，低频比较糊且肥。
OP275：和5532比，胆性还重一点，解析力、低频、音场更好一点，可以买贴片的来打摩声卡用（特别是创新的），可以改善硬冷的数码声。
EL2244：音色中性，音场比较宽，高频还可以，中频音乐味差。
有人说解析力很高，其实是因为低频量感少，中频薄，高频显得突出而已。
要用好比较难。
OP275LT1057：两端延伸不错，速度、动态和解析力也挺好，就是属冷色调，放出的音乐好象有种不食人间烟火的味道，让你可以静静的听，却燃不起对音乐的那份激情。
AD827：延伸非常好，解析力高，高频华丽，中频纯厚，低频下潜和力度都不错，音场向前后左右拓展，有了凹凸感（这一点比其它运放强），速度快，动态好，感觉很大气，初换上此运放后确实有让人为之一振的感觉。
但久听之下，也发现很多问题：一、虽然三频段、音场很宽，气势足，大开大合，但总感觉结构有点松，不够紧凑；二、人声部份一般，有时大动态时，人声被配乐声淹没；三、不够细腻，属于激情有余而柔情不足；四、音乐味不够。
不过很多的人喜欢这种风格。
当然买两片来换换口味听还是可以的，按我的感觉，用在AV功放上看DVD大片应该很适合。
OPA2604：感觉象5532的升级版，各方面都有很大提高，解析力不错，音乐味更好，有胆味，声底属于较纯厚且有点刚性，综合素质很不错。
DY649：和2604比，解析力更好，高频部份纤细而又柔美且泛音丰富，声底没2604厚，很清澈、细致的感觉，音乐画面异常清晰，人声部份圆润OPA2604DY639：整体性稍弱于649，但更具备胆机特性，胆味更浓。
DY669：和2604差不太多，纯厚的声音。
AD712：解析力很好，清晰而又没有音染的声音，一种很透明的感觉，声底细致，低频量稍少。
属于典型的监听风格。
不过可能很多人都不大喜欢这种纯净水的感觉，还是加点味精好，大概是我已前玩过音乐制作的原因吧，习惯了这种纯纯的监听味道，挺感兴趣。

DESCRIPTION
The OPA237 op amp family is one of Texas Instruments’ MicroAmplifier series of miniature products. In addition to small size, these devices feature low offset voltage, low quiescent current, low bias current, and a wide supply range. Single, dual, and quad versions have identical specifications for maximum design flexibility. They are ideal for single-supply, battery-operated, and space-limited applications, such as PCMCIA cards and other portable instruments. OPA237 series op amps can operate from either single or dual supplies. When operated from a single supply, the input common-mode range extends below ground and the output can swing to within 10mV of ground. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction. Single, dual, and quad are offered in space-saving surface-mount packages. The single version is available in the ultra-miniature 5-lead SOT23-5 and SO-8 surface-mount. The dual version comes in a miniature MSOP-8 and SO-8 surface-mount. The quad version is obsolete. MSOP-8 has the same lead count as a SO-8 but half the size. The SOT23-5 is even smaller at one-fourth the size of an SO-8. All are specified for −40°C to +85°C operation. A macromodel is available for design analysis.
