MAX4533CAP中文资料

General DescriptionThe MAX4533 quad, single-pole/double-throw (SPDT),fault-protected analog switch is pin-compatible with the industry-standard MAX333 and MAX333A. The MAX4533features fault-protected inputs and Rail-to-Rail ®signal handling. The normally open (NO_ ) and normally closed (NC_ ) terminals are protected from overvoltage faults up to ±25V with power on and up to ±40V with power off.During a fault condition, NO_ and NC_ become high impedance with only nanoamperes of leakage current flowing to the source. In addition, the output (COM_)clamps to the appropriate polarity supply rail and pro-vides up to ±10mA of load current. This ensures unam-biguous rail-to-rail outputs when a fault occurs.The MAX4533 operates from dual ±4.5V to ±18V power supplies or a single +9V to +36V supply. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply. On-resistance is 175Ωmax and is matched between switches to 10Ωmax. The off-leakage current is only 0.5nA at T A =+25°C and 10nA at T A =+85°C.ApplicationsRedundant/Backup Systems Portable Instruments Test EquipmentData-Acquisition Communications Systems SystemsIndustrial and Process ControlAvionics SystemsFeatureso Rail-to-Rail Signal Handlingo ±40V Fault Protection with Power Off±25V Fault Protection with ±15V Supplies o All Switches Off with Power Offo No Power-Supply Sequencing Required During Power-Up or Power-Down o Output Clamped to Appropriate Supply Voltage During Fault Condition—No Transition Glitch o 1k Ω(typ) Output Clamp Resistance During Overvoltage o 175Ω(max) Signal Paths with ±15V Supplies o 20ns (typ) Fault Response Time o ±4.5V to ±18V Dual Supplies +9V to +36V Single Supplyo Pin-Compatible with Industry-Standard MAX333/MAX333Ao TTL/CMOS-Compatible Logic Inputs with ±15V or Single +9V to +15V SuppliesMAX4533†Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch________________________________________________________________Maxim Integrated Products 1Typical Operating Circuit19-1452; Rev 1; 10/99Pin Configuration/Functional DiagramOrdering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.†Patent PendingFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog SwitchABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS —Dual Supplies(V+ = +15V, V- = -15V, T A = T MIN to T MAX , unless otherwise noted.

Traditional fault-pro-tected switches are constructed using three-series CMOS devices. This combination produces good fault protection but fairly high on-resistance when the signals are within about 3V of each supply rail. These series devices are not capable of handling signals up to the power-supply rails.The MAX4533 differs considerably from traditional fault-protected switches, with three advantages. First, it is constructed with two parallel FETs, allowing very low on-resistance when the switch is on. Second, they allow signals on the NC_ or NO_ pins that are within or slightlybeyond the supply rails to be passed through the switch to the COM_ terminal, allowing rail-to-rail signal opera-tion. Third, when a signal on NC_ or NO_ exceeds the supply rails by about 150mV (a fault condition), the volt-age on COM_ is limited to the appropriate polarity sup-ply voltage. Operation is identical for both fault polarities. The fault-protection extends to ±25V with power on and ±40V with power off.The MAX4533 has a parallel N-channel and P-channel MOSFET switch configuration with input voltage sensors.The simplified internal structure is shown in Figure 1. The parallel N1 and P1 MOSFETs form the switch element.N3 and P3 are sensor elements to sample the input volt-age and compare it against the power-supply rails.*When the voltage on NO_ or NC_ does not exceed V+ or V-, NO_ (or NC_) and COM_ pins are bidirectional.During normal operation of a conducting channel, N1and P1 remain on with a typical 125Ωon-resistance between NO_ (or NC_) and COM_. If the input voltage exceeds either supply rail by about 150mV, the parallel combination switches (N1, P1) are forced off through the driver and sensing circuitries. At the same time, the output (COM_ ) is clamped to the appropriate supply rail by the clamp circuitries (N2, P2). Two clamp circuits limit the output voltage to the supply voltages.For simplicity, Figure 1 shows only one side of the SPDT switch configuration. The complete circuit is composed of two channels with their outputs connected.Normal OperationTwo comparators continuously compare the voltage on the NO_ (or NC_ ) pin with V+ and V- supply voltages.When the signal on NO_ (or NC_ ) is between V+ and V-, the switch behaves normally, with FETs N1 and P1turning on and off in response to NO_ (or NC_) signals (Figure 1). For any voltage between the supply rails,the switch is bidirectional; therefore, COM_ and NC_(or NO_ ) are interchangeable. Only NO_ and NC_ can be exposed to overvoltages beyond the supply range and within the specified breakdown limits of the device.Fault ConditionThe MAX4533 protects devices connected to its output (COM_) through its unique fault-protection circuitry.When the input voltage is raised above either supply rail, the internal sense and comparator circuitries (N3and N-channel driver or P3 and P-channel driver) dis-connect the output (COM_) from the input (Figure 1).If the switch driven above the supply rail has an on state, the clamp circuitries (N2 or P2) connect the out-put to the appropriate supply rail. Table 1 summarizes the MAX4533’s operation under normal and fault condi-tions. Row 5 shows a negative fault condition when the supplies are on. It shows that with supplies of ±15V, if the input voltage is between -15V and -25V, the output (COM_) clamps to the negative supply rail of -15V.With this technique, the SPDT switch is capable of with-standing a worse-case condition of opposite fault polar-ities at its inputs.Transient Fault ConditionWhen a fast rising or falling transient on NO_ (or NC_)exceeds V+ or V-, the output (COM_) follows the input (IN_) to the supply rail by only a few nanoseconds. This delay is due to the switch on-resistance and circuit capacitance to ground. However, when the input tran-sient returns to within the supply rails there is a longer recovery time. For positive faults, the recovery time is typically 2.5µs. For negative faults, the recovery time is typically 1.3µs. These values depend on the COM_ out-put resistance and capacitance. The delays are not dependent on the fault amplitude. Higher COM_ output resistance and capacitance increase the recovery times.Fault Protection, Voltage, and Power OffThe maximum fault voltage on the NO_ or NC_ pins is ±40V from ground when the power is off. With ±15V sup-ply voltages, the highest voltage on NO_ (or NC_) can be +25V, and the lowest voltage on NO_ (or NC_) can be -25V. Exceeding these limits can damage the chip.IN_ Logic-Level ThresholdsThe logic-level thresholds are TTL/CMOS-compatible when V+ is +15V. Raising V+ increases the threshold slightly; when V+ reaches +25V, the level threshold is 2.8V—higher than the TTL output high-level minimum of 2.4V, but still compatible with CMOS outputs (see the Typical Operating Characteristics ).Increasing V- has no effect on the logic-level thresh-olds, but it does increase the gate-drive voltage to the signal FETs, reducing their on-resistance.MAX4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch_______________________________________________________________________________________9Figure 1. Simplified Internal StructureFailure ModesThe MAX4533 is not a lightning arrester or surge pro-tector. Exceeding the fault-protection voltage limits on NO_ or NC_, even for very short periods, can cause the device to fail.Applications InformationGroundThere is no connection between the analog signal paths and GND. The analog signal paths consist of an N-channel and P-channel MOSFET with their sources and drains paralleled and their gates driven out of phase to V+ and V- by the logic-level translators.V+ and GND power the internal logic and logic-level translators and set the input logic thresholds. The logic-level translators convert the logic levels to switched V+and V- signals to drive the gates of the switches. Thisdrive signal is the only connection between the power supplies and the analog signals. GND, IN_, and COM_have ESD protection diodes to V+ and V-.Supply Current ReductionWhen the logic signals are driven rail-to-rail from 0 to +12V or -15V to +15V, the supply current reduces to approximately half of the supply current when the logic input levels are at 0 to 5V.Power SuppliesThe MAX4533 operates with bipolar supplies between ±4.5V and ±18V. The V+ and V- supplies need not be symmetrical, but their difference can not exceed the absolute maximum rating of +44V. The MAX4533 oper-ates from a single supply between +9V and +36V when V- is connected to GND.M A X 4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch 10______________________________________________________________________________________Table 1.

The MAX5481/MAX5482 are 3-terminal voltage-dividers and the MAX5483/MAX5484are 2-terminal variable resistors.The MAX5481–MAX5484 feature an internal, non-volatile, electrically erasable programmable read-only memory (EEPROM) that stores the wiper position for ini-tialization during power-up. The 3-wire SPI-compatible serial interface allows communication at data rates up to 7MHz. A pin-selectable up/down digital interface is also available.The MAX5481–MAX5484 are ideal for applications requiring digitally controlled potentiometers. Two end-to-end resistance values are available (10k Ωand 50k Ω) in a voltage-divider or a variable-resistor configuration (see the Selector G uide ). The nominal resistor temperature coefficient is 35ppm/°C end-to-end, and only 5ppm/°C ratiometric, making these devices ideal for applications requiring low-temperature-coefficient voltage-dividers,such as low-drift, programmable gain-amplifiers.The MAX5481–MAX5484 operate with either a +2.7V to +5.25V single power supply or ±2.5V dual power sup-plies. These devices consume 400µA (max) of supply current when writing data to the nonvolatile memory and 1.0µA (max) of standby supply current. The MAX5481–MAX5484 are available in a space-saving (3mm x 3mm), 16-pin TQFN, or a 14-pin TSSOP pack-age and are specified over the extended (-40°C to +85°C) temperature range.ApplicationsFeatures♦1024 Tap Positions♦Power-On Recall of Wiper Position from Nonvolatile Memory♦16-Pin (3mm x 3mm x 0.8mm) TQFN or 14-Pin TSSOP Package♦35ppm/°C End-to-End Resistance Temperature Coefficient♦5ppm/°C Ratiometric Temperature Coefficient ♦10kΩand 50kΩEnd-to-End Resistor Values♦Pin-Selectable SPI-Compatible Serial Interface or Up/Down Digital Interface ♦1µA (max) Standby Current♦Single +2.7V to +5.25V Supply Operation ♦Dual ±2.5V Supply OperationMAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometers________________________________________________________________Maxim Integrated Products1Ordering InformationPin Configurations19-3708; Rev 5; 4/10For pricing delivery, and ordering information please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .Selector Guide appears at end of data sheet.SPI is a trademark of Motorola, Inc.temperature range.+Denotes a lead(Pb)-free/RoHS-compliant package.*EP = Exposed pad.Ordering Information continued at end of data sheet.Gain and Offset AdjustmentLCD Contrast Adjustment Pressure SensorsLow-Drift Programmable Gain AmplifiersMechanical Potentiometer ReplacementM A X 5481–M A X 548410-Bit, Nonvolatile, Linear-Taper Digital PotentiometersABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

programmable voltage-dividers and the MAX5483/MAX5484 variable resistors feature 1024 tap points (10-bit resolution) (see the Functional Diagrams ). These devices consist of multi-ple strings of equal resistor segments with a wiper con-tact that moves among the 1024 points through a pin-selectable 3-wire SPI-compatible serial interface or up/down interface. The MAX5481/MAX5483 provide a total end-to-end resistance of 10k Ω, and the MAX5482/MAX5484 have an end-to-end resistance of 50k Ω. The MAX5481/MAX5482 allow access to the high, low, and wiper terminals for a standard voltage-divider configuration.MAX5481/MAX5482 ProgrammableVoltage-DividersThe MAX5481/MAX5482 programmable voltage-dividers provide a weighted average of the voltage between the H and L inputs at the W output. Both devices feature 10-bit resolution and provide up to 1024 tap points between the H and L voltages. Ideally,the V L voltage occurs at the wiper terminal (W) when all data bits are zero and the V H voltage occurs at the wiper terminal when all data bits are one. The step size (1 LSB) voltage is equal to the voltage applied across terminals H and L divided by 210. Calculate the wiper voltage V Was follows:Functional Diagrams (continued)MAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometerswhere D is the decimal equivalent of the 10 data bits writ-ten (0 to 1023), V HL is the voltage difference between the H and L terminals:The MAX5481 includes a total end-to-end resistance value of 10k Ωwhile the MAX5482 features an end-to-end resistance value of 50k Ω. These devices are not intended to be used as a variable resistor . Wiper cur-rent creates a nonlinear voltage drop in series with the wiper. To ensure temperature drift remains within speci-fications, do not pull current through the voltage-divider wiper. Connect the wiper to a high-impedance node.Figures 1 and 2 show the behavior of the MAX5481’s resistance from W to H and from W to L. This does not apply to the variable-resistor devicesMAX5483/MAX5484 Variable ResistorsThe MAX5483/MAX5484 provide a programmable resistance between W and L. The MAX5483 features a total end-to-end resistance value of 10k Ω, while the MAX5484 provides an end-to-end resistance value of 50k Ω. The programmable resolution of this resistance is equal to the nominal end-to-end resistance divided by 1024 (10-bit resolution). For example, each nominal segment resistance is 9.8Ωand 48.8Ωfor the MAX5483and the MAX5484, respectively.wiper position from the 1024 possible positions, result-ing in 1024 values for the resistance from W to L.Calculate the resistance from W to L (R WL ) by using the where D is decimal equivalent of the 10 data bits writ-ten, R W-L is the nominal end-to-end resistance, and R Z is the zero-scale error. Table 1 shows the values of R WL at selected codes for the MAX5483/MAX5484.Digital InterfaceConfigure the MAX5481–MAX5484 by a pin-selectable,3-wire, SPI-compatible serial data interface or an up/down interface.

This write-only interface contains three inputs: chip select (CS ), data in (DIN(U/D )), and data clock (SCLK(INC )). Drive CS low to load the data at DIN(U/D ) synchronously into the shift register on each SCLK(INC ) rising edge.The WRITE command (C1, C0 = 00) requires 24 clock cycles to transfer the command and data (Figure 4a).The COPY commands (C1, C0 = 10 or 11) use either eight clock cycles to transfer the command bits (Figure 4b) or 24 clock cycles with the last 16 data bits disre-garded by the device.After loading the data into the shift register, drive CS high to latch the data into the appropriate control regis-ter. Keep CS low during the entire serial data stream to avoid corruption of the data. Table 2 shows the com-mand decoding.Write Wiper RegisterData written to this register (C1, C0 = 00) controls the wiper position. The 10 data bits (D9–D0) indicate the position of the wiper. For example, if DIN(U/D ) = 00 00000000, the wiper moves to the position closest to L. If DIN(U/D ) = 11 1111 1111, the wiper moves closest to H.This command writes data to the volatile random access memory (RAM), leaving the NV register unchanged. When the device powers up, the data stored in the NV register transfers to the wiper register,moving the wiper to the stored position. Figure 5 shows how to write data to the wiper register.Table 2.

Write Wiper Register OperationM A X 5481–M A X 548410-Bit, Nonvolatile, Linear-Taper Digital Potentiometers Copy Wiper Register to NV RegisterThe copy wiper register to NV register command (C1,C0 = 10) stores the current position of the wiper to the NV register for use at power-up. Figure 6 shows how to copy data from wiper register to NV register. The oper-ation takes up to 12ms (max) after CS goes high to complete and no other operation should be performed until completion.Copy NV Register to Wiper RegisterThe copy NV register to wiper register (C1, C0 = 11)restores the wiper position to the current value stored in the NV register. Figure 7 shows how to copy data from the NV register to the wiper register.Digital Up/Down InterfaceFigure 8 illustrates an up/down serial-interface timing diagram. In digital up/down interface mode (SPI/UD =0), the logic inputs CS , DIN(U/D ), and SCLK(INC ) con-trol the wiper position and store it in nonvolatile memory (see Table 3). The chip-select (CS ) input enables the serial interface when low and disables the interface when high. The position of the wiper is stored in the nonvolatile register when CS transitions from low to high while SCLK(INC ) is high.When the serial interface is active (CS low), a high-to-low (falling edge) transition on SCLK(INC ) increments or decrements the internal 10-bit counter depending on the state of DIN(U/D ). If DIN(U/D ) is high, the wiper increments. If DIN(U/D ) is low, the wiper decrements.The device stores the value of the wiper position in the nonvolatile memory when CS transitions from low to high while SCLK(INC ) is high. The host system can disablethe serial interface and deselect the device without stor-ing the latest wiper position in the nonvolatile memory by keeping SCLK(INC ) low while taking CS high.Upon power-up, the MAX5481–MAX5484 load the value of nonvolatile memory into the wiper register, and set the wiper position to the value last stored.Figure 6.

Copy NV Register to Wiper Register OperationMAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometersStandby ModeThe MAX5481–MAX5484 feature a low-power standby mode. When the device is not being programmed, it enters into standby mode and supply current drops to 0.5µA (typ).Nonvolatile MemoryThe internal EEPROM consists of a nonvolatile register that retains the last value stored prior to power-down.The nonvolatile register is programmed to midscale at the factory. The nonvolatile memory is guaranteed for 50 years of wiper data retention and up to 200,000wiper write cycles.Power-UpUpon power-up, the MAX5481–MAX5484 load the data stored in the nonvolatile wiper register into the volatile wiper register, updating the wiper position with the data stored in the nonvolatile wiper register.Applications InformationThe MAX5481–MAX5484 are ideal for circuits requiring digitally controlled adjustable resistance, such as LCD contrast control (where voltage biasing adjusts the dis-play contrast), or programmable filters with adjustable gain and/or cutoff frequency.Positive LCD Bias ControlFigures 9 and 10 show an application where a voltage-divider or a variable resistor is used to make an adjustable, positive LCD-bias voltage. The op amp pro-vides buffering and gain to the voltage-divider network made by the programmable voltage-divider (Figure 9) or to a fixed resistor and a variable resistor (see Figure 10).Programmable Gain and Offset AdjustmentFigure 11 shows an application where a voltage-divider and a variable resistor are used to make a programma-ble gain and offset adjustment.Figure 8.

MAX14595ETA+T MAX14595低功耗双通道逻辑级转换器说明书

MAX14595ETA+TMAX14595 Low-Power Dual-Channel Logic-Level TranslatorGeneral DescriptionThe MAX14595 is a dual-channel, bidirectional logic-level translator designed specifically for low power consumption making it suitable for portable and battery-powered equipment. Externally applied voltages, V CC and V L, set the logic levels on either side of the device. A logic signal present on the V L side of the device appears as the same logic signal on the V CC side of the device, and vice-versa.The device is optimized for the I2C bus as well as the management data input/output (MDIO) bus where often high-speed, open-drain operation is required. When TS is high, the device allows the pullup to be connected to the I/O port that has the power. This allows continuous I2C operation on the powered side without any disruption while the level translation function is off.The part is specified over the extended -40N C to +85N C temperature range, and is available in 8-bump WLP and 8-pin TDFN packages.ApplicationsPortable and Battery-Powered ElectronicsDevices with I2C CommunicationDevices with MDIO CommunicationGeneral Logic-Level TranslationBenefits and Features S Meets Industry Standards✧ I2C Requirements for Standard, Fast, and High* Speeds✧ MDIO Open Drain Above 4MHz*S Allows Greater Design Flexibility✧ Down to 0.9V Operation on V L Side✧ Supports Above 8MHz Push-Pull OperationS Ultra-Low Power Consumption✧ 7µA V CC Supply Current✧ 3µA V L Supply CurrentS Provides High Level of Integration✧ Pullup Resistor Enabled with One Side PowerSupply when TS Is High✧ 12k I (max) Internal Pullup✧ Low Transmission Gate R ON: 17I (max)S Saves Space✧ 8-Bump, 0.4mm Pitch, 0.8mm x 1.6mm WLPPackage✧ 8-Pin, 2mm x 2mm TDFN PackageTypical Operating Circuit Ordering Information appears at end of data sheet.For related parts and recommended products to use with this part, refer to /MAX14595.related.*Requires external pullups.EVALUATION KIT AVAILABLEMAX14595Low-Power Dual-Channel Logic-Level TranslatorVoltages referenced to GND.V CC , V L , TS .............................................................-0.5V to +6V IOVCC1, IOVCC2 ...................................-0.5V to +(V CC + 0.5V)IOVL1, IOVL2 ............................................-0.5V to +(V L + 0.5V)Short-Circuit Duration IOVCC1, IOVCC2,IOVL1, IOVL2 to GND ...........................................Continuous V CC , IOVCC_ Maximum Continuous Current at +110N C ....100mA V L IOVL_ Maximum Continuous Current at +110N C ..........40mATS Maximum Continuous Current at +110N C .....................70mA Continuous Power Dissipation (T A = +70N C)TDFN (derate 6.2mW/N C above +70N C) ......................496mW WLP (derate 11.8mW/N C above +70N C)......................944mW Operating Temperature Range ..........................-40N C to +85N C Storage Temperature Range ............................-65N C to +150N C Lead Temperature (TDFN only, soldering, 10s) .............+300N C Soldering Temperature (reflow) ......................................+260N CTDFNJunction-to-Ambient Thermal Resistance (B JA ) ........162N C/W Junction-to-Case Thermal Resistance (B JC ) ...............20N C/WWLPJunction-to-Ambient Thermal Resistance (B JA ) ..........85N C/WABSOLUTE MAXIMUM RATINGSNote 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layerboard.

The device translates low voltage down to +0.9V on the V L side to high voltage on the V CC side and vice-ver-sa. The device is optimized for open-drain and high-speed operation, such as I2C bus and MDIO bus.The device has low on-resistance (17I max), which is important for high-speed, open-drain operation. The device also features internal pullup resistors that are active when the corresponding power is on and TS is high.Level Translation For proper operation, ensure that +1.65V P V CC P +5.5V, and +0.9V P V L P V CC. When power is supplied to V L while V CC is less than V L, the device automatically disables logic-level translation function. Also, the device enters shutdown mode when TS = GND.High-Speed Operation The device meets the requirements of high-speed I2C and MDIO open-drain operation. The maximum data rate is at least 4MH z for open-drain operation with the total bus capacitance equal to or less than 100pF.Three-State Input TS The device features a three-state input that can put the device into high-impedance mode. When TS is low, IOVCC_ and IOVL_ are all high impedance and the inter-nal pullup resistors are disconnected. When TS is high, the internal pullup resistors are connected when the corresponding power is in regulation, and the resistors are disconnected at the side that has no power on. In many portable applications, one supply is turned off but the other side is still operating and requires the pullup resistors to be present. This feature eliminates the need for external pullup resistors. The level translation function is off until both power supplies are in range.Thermal-Shutdown Protection The device features thermal-shutdown protection to protect the part from overheating. The device enters thermal shutdown when the junction temperature exceeds +150N C (typ), and the device is back to normal operation again after the temperature drops by approximately 10N C (typ). When the device is in thermal shutdown, the level translator is disabled.Low-Power Dual-Channel Logic-Level Translator10Maxim Integrated Ordering InformationNote: All devices are specified over -40°C to +85°C operating temperature range.+Denotes a lead(Pb)-free/RoHS-compliant package.T = Tape and reel.Chip InformationPROCESS: BiCMOSPackage InformationFor the latest package outline information and land patterns (foot-prints), go to /packages .
