MAX809 Series,MAX810 SeriesVery Low Supply Current3−Pin MicroprocessorReset MonitorsThe MAX809 and MAX810 are cost−effective system supervisor circuits designed to monitor V CC in digital systems and provide a reset signal to the host processor when necessary. No external components are required.The reset output is driven active within 10 m sec of V CC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by the factory after V CC rises above the reset threshold. The MAX810 has an active−high RESET output while the MAX809 has an active−low RESET output. Both devices are available in SOT−23 and SC−70 packages.The MAX809/810 are optimized to reject fast transient glitches on the V CC line. Low supply current of 0.5 m A (V CC= 3.2 V) makes these devices suitable for battery powered applications.Features•Precision V CC Monitor for 1.5 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, and 5.0 V Supplies•Precision Monitoring V oltages from 1.2 V to 4.9 V Availablein 100 mV Steps•Four Guaranteed Minimum Power−On Reset Pulse Width Available (1 ms, 20 ms, 100 ms, and 140 ms)•RESET Output Guaranteed to V CC = 1.0 V.•Low Supply Current•Compatible with Hot Plug Applications•V CC Transient Immunity•No External Components•Wide Operating Temperature: −40°C to 105°C•Pb−Free Packages are AvailableTypical Applications•Computers•Embedded Systems•Battery Powered Equipment•Critical Microprocessor Power Supply MonitoringV CCFigure 1.

Normalized Power−Up Reset vs.Temperature10050751.01.110050APPLICATIONS INFORMATIONV CC Transient RejectionThe MAX809 provides accurate V CC monitoring and reset timing during power−up, power−down, and brownout/sag conditions, and rejects negative−going transients (glitches) on the power supply line. Figure 13shows the maximum transient duration vs. maximum negative excursion (overdrive) for glitch rejection. Any combination of duration and overdrive which lies under the curve will not generate a reset signal. Combinations above the curve are detected as a brownout or power−down.Typically, transient that goes 100 mV below the reset threshold and lasts 5.0 m s or less will not cause a reset pulse.Transient immunity can be improved by adding a capacitor in close proximity to the V CC pin of the MAX809.Figure 13.

This means CMOS logic inputs to the Microprocessor will be floating at an undetermined voltage.Most digital systems are completely shutdown well above this voltage. However, in situations where RESET must bemaintained valid to V CC = 0 V , a pull−down resistor must be connected from RESET to ground to discharge stray capacitances and hold the output low (Figure 14). This resistor value, though not critical, should be chosen such that it does not appreciably load RESET under normal operation (100 k W will be suitable for most applications).Figure 14. Ensuring RESET Valid to V CC = 0 VProcessors With Bidirectional I/O PinsSome Microprocessor’s have bidirectional reset pins.Depending on the current drive capability of the processor pin, an indeterminate logic level may result if there is a logic conflict. This can be avoided by adding a 4.7 k W resistor in series with the output of the MAX809 (Figure 15). If there are other components in the system which require a reset signal, they should be buffered so as not to load the reset line.If the other components are required to follow the reset I/O of the Microprocessor, the buffer should be connected as shown with the solid line.Figure 15.

MAX2605-MAX2609中文资料

General DescriptionThe MAX2605–MAX2609 evaluation kits (EV kits) simplify evaluation of this family of voltage-controlled oscillators (VCOs). These kits enable testing of the devices’ per-formance and require no additional support circuitry.Both signal outputs use SMA connectors to facilitate connection to RF test equipment.These EV kits are fully assembled and tested. Their oscil-lation frequencies are set to approximately the midrange of the respective VCOs.Featureso Easy Evaluationo Complete, Tunable VCO Test Board with Tank Circuit o Low Phase Noiseo Fully Assembled and TestedEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits19-1673 Rev 0; 9/00Ordering InformationComponent SuppliersFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.MAX2606 Component ListMAX2605 Component ListE v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 2_______________________________________________________________________________________Quick StartThe MAX2605–MAX2609 evaluation kits are fully assembled and factory tested. Follow the instructions in the Connections a nd Setup section for proper device evaluation.Test Equipment Required•Low-noise power supplies (these are recommended for oscillator noise measurement). Noise or ripple will frequency-modulate the oscillator and cause spectral spreading. Batteries can be used in place of power supplies, if necessary.– Use a DC power supply capable of supplying +2.7V to +5.5V. Alternatively, use two or three 1.5V batteries.– Use a DC power supply capable of supplying +0.4V to +2.4V, continuously variable, for TUNE.Alternatively, use two 1.5V batteries with a resistive voltage divider or potentiometer.•An RF spectrum analyzer that covers the operating frequency range of the MAX2605–MAX2609• A 50Ωcoaxial cable with SMA connectors •An ammeter (optional)Connections and Setup1)Connect a DC supply (preset to +3V) to the V CC and GND terminals (through an ammeter, if desired) on the EV kit.2)Turn on the DC supply. If used, the ammeter readingMAX2607 Component ListMAX2608 Component ListEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits_______________________________________________________________________________________3approximates the typical operating current specified in the MAX2605–MAX2609 data sheet.3)Connect the VCO output (OUT+ or OUT-) to a spec-trum analyzer with a 50Ωcoaxial cable.4)Apply a positive variable DC voltage between 0.4V and 2.4V to TUNE.5)Check the tuning bandwidth on the spectrum analyz-er by varying the tuning voltage (+0.4V to +2.4V).Layout ConsiderationsThe EV kit PC board can serve as a guide for laying out a board using the MAX2605–MAX2609. Generally, the VCC pin on the PC board should have a decoupling capacitor placed close to the IC. This minimizes noisecoupling from the supply. Also, place the VCO as far away as possible from the noisy section of a larger sys-tem, such as a switching regulator or digital circuits.The VCO ’s performance is strongly dependent on the availability of the external tuning inductor. For best per-formance, use high-Q components and choose their val-ues carefully. To minimize the effects of parasitic ele-ments, which degrade circuit performance, place the tuning inductor and C BYP close to the VCO. For higher-frequency versions, include the parasitic PC board inductance and capacitance when calculating the oscillation frequency. In addition, remove the ground plane around and under the tuning inductor to minimize the effect of parasitic capacitance.Noise on TUNE translates into FM noise on the outputs;therefore, keep the trace between TUNE and the control circuitry as short as possible. If necessary, use an RC filter to further suppress noise, as done on the EV kits.E v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 4_______________________________________________________________________________________Figure 2.

LED lighting, muting drive output, stop signal (SD).• For LED lighting, muting drive output, stop signal, the output at pin 8 is used.• The voltage on pin 8, when tuned, turns from "H" to "L".(Active-Low)• Signal bandwidth at pin 8.– For AM, the bandwidth depends on the CF (BFU450CN) at pin 11. If a capacitor is connected in place of the CF, the bandwidth will get wider.– For FM, the bandwidth depends on the resistance across pins 9 and 22. If the resistance is increased, the bandwidth will get narrower. R=15k Ωmakes the bandwidth approximately120kHz.• Sensitivity adjustment of LED, muting, stop signal.– For FM, the semifixed variable resistor across pin 15 and GND is used.– For AM, the semifixed variable resistor across pins 15 and 16 is used. Be sure to start adjustment for FM, and then make adjustment for AM. For the stop signal sensitivity and FM stop signal bandwidth, the variations should be considered and it is recommended to use the semifixed variable resistor for adjustment. • LED lighting sensitivity setting for AM.For the LED lighting sensitivity setting for AM, it is desirable that the IC input be 30dBµ(antenna input :approximately 50dB/m). In this case, the value of VR1 is 30k Ω.Equivalent Circuit Block DiagramResistance across pins 9 and 22 – k ΩLED Lighting Bandwidth – Resistance across pins 9 and 22L E D l i g h t i n g b a n d w i d t h – k H z3. Local OSC buffer output• When local OSC buffer output wave form is saw-toothed at the SW mode, connect a resistance of 1.2k Ωor thereabouts across pin 24 and GND.4. AM input pin• It is desirable that the AM input pin (pin 21) be L-coupled to pin 20.• Inputting to pin 21 can be done by DC-cutting with a capacitor. However, an unbalance in the RF amplifier(differential amplifier) causes gain drop and whistle worsening.5. Capacitance across pin 9 and GND.A large capacitance across pin 9 and GND may cause a misstop at an adjacent channel when the channel select speed is made faster at the automatic channel select mode. In this case, decrease the capacitance across pin 9 and GND. However, if toodecreased, the LED will flutter at low modulation frequencies at the time of detuning. Therefore, it is recommended to fix the capacitance across pin 9 and GND to be 3.3µF to 10µF. The relation between modulation frequency and demodulation output voltage on pin 9 with the capacitance across pin 9 and GND as a parameter is shown right.• LED lighting sensitivity setting for FM.For the LED lighting sensitivity setting for FM, the IC inputmay be 45dBµto 60dBµ. With the variations in the front endconsidered, it is ideal that the IC input in a standard receiving set be 51dBµto 54dBµ. The lower value of VR2 for theLED lighting sensitivity setting is as illustrated right. Sincethe variations in the front end cause the IC input setting sensitivity to vary, it is recommended to use a value of VR2at an input voltage lower than a standard setting by 6dB or greater. For example, if IC input 53dBµis taken as a standard, use VR2≤100k Ωat IC input 47dBµ.2. AM/FM changeover• Two selections are available for changeover as shown below: (A) pin 19-used method and (B) pin 20-used method.• For (A), the voltage on pin 19 relative to V CC (pin 7) must be within the range of –0.8V to +0.1V. If not within this range, distortion and selectivity will get worse.• For (A), a resistance of 68k Ωat the IFT cold terminal, which is used to prevent the changeover circuit from malfunctioning, must be connected.(A) pin 19-use method for AM/FM changeover (B) Pin 20-used method for AM/FM changeoverIC input – dBµSemifixed Variable Resistor for FMV R 2 s e m i f i x e d v a r i a b l e r e s i s t o r v a l u e – k ΩLED lighting sensitivity setting for FM Ideal setting range Modulation frequency – HzV9 – Modulation FrequencyFM6. If the coupling coefficient of the local OSC coil is small and an antiresonance point of approximately 100MHz is present or the stray capacitance across pins 24 and 23 is large, a parasitic oscillation of approximately 100MHz may occur in the buffer output (pin 24). In this case, connect a capacitance of approximately 30pF across pin 24 and GND.7. AM OSC coilGenerally speaking, the following should be noted. Avoid winding with loose coupling between primary side and secondary side (especially SW1, SW2). To put it concretely, the pot core type is better than the screw core type which is loose in coupling. This prevents the local OSC frequency from turning third resonance frequency related to the coupling coefficient.8. Resistance across pin 8 and V DD .If pin 8 is used for the stop signal (SD) only, without using LED, it is recommended to fix resistance R L across pin 8and GND to be 51k Ωto 100k Ω.9. To prevent whistle from worsening, make the pattern of AM output pin 14 as short as possible.Input/Output AdmittanceTest Circuit : FM, AM-MWT1 : 4147-1457-177 (Sumida)T2 : HW-40174 (Mitsumi)T3 :

MAX14878-MAX14880 高速传输接收器的中文名字说明书

General DescriptionThe MAX14878–MAX14880family of high-speed trans-ceivers improve communication and safety by integrating galvanic isolation between the CAN protocol controller side of the device and the physical wires of the network (CAN)bus.Isolation improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between ports.The MAX14879provides up to2750V RMS(60s)of galvanic isolation,while the MAX14878/MAX14880provide up to 5000V RMS(60s)of galvanic isolation in8-pin and16-pin SOIC packages.All transceivers operate up to the maximum high-speed CAN data rate of1Mbps.The MAX14879/MAX14880fea-ture an integrated standby input(STB)on the isolated side of the transceiver to disable the driver and place the trans-ceiver in a low-power standby mode.The MAX14878does not include the standby input.The MAX14878–MAX14880transceivers feature integrat-ed protection for robust communication.The receiver input common-mode range is±25V,exceeding the ISO11898 specification of-2V to+7V,and are fault tolerant up to ±54V.Driver outputs/receiver inputs are also protected from±15kV electrostatic discharge(ESD)to GNDB on the bus side, as specified by the Human Body Model (HBM). Interfacing with CAN protocol controllers is simplified by the wide1.71V to5.5V supply voltage range(V DDA)on the controller side of the device.This supply voltage sets the interface logic levels between the transceiver and con-troller.The supply voltage range for the CAN bus side of the device is 4.5V to 5.5V (V DDB).The MAX14878–MAX14880are available in a wide-body 16-pin SOIC package with8mm of creepage and clear-ance.The MAX14878is also available in8-pin wide-body SOIC packages with5mm(MAX14878)and8mm (MAX14878W)creepage.All devices operate over the -40°C to +125°C temperature range.Applications●Industrial Controls●HVAC●Building Automation●Switching Gear Benefits and Features●Integrated Protection for Robust Communication• 2.75kV RMS, 3.5kV RMS, or 5kV RMS Withstand Isolation Voltage for 60s (Galvanic Isolation)•±25V Receiver Input Common-Mode Range•±54V Fault Protection on Receiver Inputs●High-Performance Transceiver Enables FlexibleDesigns•Wide 1.71V to 5.5V Supply for the CAN Controller Interface•Available 16-pin and 8-pin SOIC Package Pin Configurations•Data Rates up to 1Mbps (Max)•Dominant Timeout ProtectionSafety Regulatory Approvals●UL According to UL1577 (Basic Insulation) (16-PinPackage Devices Only)Ordering Information appears at end of data sheet.Click here to ask about the production status of specific part numbers.MAX14878–MAX14880 2.75kV, 3.5kV, and 5kV Isolated CANTransceiversSimplified Block DiagramAbsolute Maximum RatingsV DDA to GNDA.........................................................-0.3V to +6V V DDB to GNDB.........................................................-0.3V to +6V TXD to GNDA...........................................................-0.3V to +6V RXD to GNDA...........................................-0.3V to (V DDA+ 0.3V) STB to GNDB...........................................................-0.3V to +6V I.C. to GNDB.............................................-0.3V to (V DDB+ 0.3V) CANH or CANL to GNDB, (Continuous).................-54V to +54V Short-Circuit Duration (CANH to CANL).....................Continuous Short-Circuit Duration (RXD to GNDA or V DDA)........Continuous Continuous Power Dissipation (T A= +70ºC)16-pin W SOIC (derate 14.1mW/°C above +70°C)..1126.8mW 8-pin W SOICW8MS+1 (derate 9.39mW/°C above +70°C)........751.17mW W8MS+5 (derate 11.35mW/°C above +70°C)......908.06mW Operating Temperature Range.............................-40ºC to 125ºC Junction Temperature.......................................................+150ºC Storage Temperature Range..............................-60ºC to +150ºC Lead Temperature (soldering, 10s)...................................+300ºC Soldering Temperature (reflow)........................................+260ºCNOTE:See the Isolation section of the Electrical Characteristics table for maximum voltage from GNDA to GNDBStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Bypass V DDBto GNDB with a 0.1μF capacitoras close to the device aspossible.V DDB PowerDetailed DescriptionThe MAX14878–MAX14880isolated controller area network(CAN)transceivers provide2750V RMS or5000V RMS(60s) of galvanic isolation between the cable side(B-side)of the transceiver and the controller side(A-side).These devices allow up to1Mbps communication across an isolation barrier when a large potential exists between grounds on each side of the barrier.CANH and CANL outputs are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs in a high-impedance state.IsolationData isolation is achieved using integrated capacitive isolation that allows data transmission between the controller side and cable side of the transceiver.Fault ProtectionThe MAX14878–MAX14880feature±54V fault protection on the CANH and CANL bus lines.When CANH or CANL is pulled above+30V(typ)or below-30V(typ),the I/O is set to high impedance.This wide fault protection range simplifies selecting external TVS components for surge protection.TransmitterThe transmitter converts a single-ended input signal(TXD)from the CAN controller to differential outputs for the bus lines (CANH, CANL). The truth table for the transmitter and receiver is given in Table 1.Transmitter Dominant TimeoutThe MAX14878–MAX14880feature a transmitter-dominant timeout(t DOM)that prevents erroneous CAN controllers from clamping the bus to a dominant level by maintaining a continuous low TXD signal.When TXD remains in the dominant state (low) for greater than t DOM, the transmitter is disabled, releasing the bus to a recessive state (Table 1).After a dominant timeout fault, normal transmitter function is re-enabled on the rising edge of a TXD.The transmitter-dominant timeout limits the minimum possible data rate to 9kbps for standard CAN protocol.Driver Output ProtectionThe MAX14878–MAX14880feature integrated circuitry to protect the transmitter output stage against a short-circuit to a positive or negative voltage by limiting the driver current.The transmitter returns to normal operation once the short is removed.Thermal shutdown further protects the transceiver from excessive temperatures that may result from a short by setting the transmitter outputs to high impedance when the junction temperature exceeds+160°C(typ).The transmitter returns to normal operation when the junction temperature falls below the thermal shutdown hysteresis.ReceiverThe receiver reads the differential input from the bus(CANH,CANL)and transfers this data as a single-ended output (RXD)to the CAN controller.During normal operation,a comparator senses the difference between CANH and CANL, V DIFF=(V CANH-V CANL),with respect to an internal threshold of0.7V(typ).If V DIFF>0.9V,a logic-low is present on RXD. If V DIFF< 0.5V, a logic-high is present.The CANH and CANL common-mode range is±25V.RXD is logic-high when CANH and CANL are shorted or terminated and undriven.Thermal ShutdownIf the junction temperature exceeds+160°C(typ),the device is switched off.During thermal shutdown,CANH and CANL are high-impedance and all IC functions are disabled.The transmitter outputs are re-enabled and the device resumes normal operation when the junction temperature drops below 147°C (typ).Table 1.

A star configuration should never be used.Any deviation from the end-to-end wiring scheme creates a stub.High-speed data edges on a stub can create reflections back down the bus.These reflections can cause data errors by eroding the noise margin of the system.Although stubs are unavoidable in a multidrop system,care should be taken to keep these stubs as short as possible,especially when operating with high data rates.Typical Operating CircuitOrdering InformationPART NUMBER ISOLATION VOLTAGE (kV RMS)STANDBY OPERATING TEMPERATURE PACKAGE MAX14878AWA+ 3.5NO-40°C to +125°C W 8-SOIC MAX14878AWA+T 3.5NO-40°C to +125°C W 8-SOIC MAX14878AWE+5NO-40°C to +125°C W 16-SOIC MAX14878AWE+T5NO-40°C to +125°C W 16-SOIC MAX14878WAWA+5NO-40°C to +125°C W 8-SOIC MAX14878WAWA+T5NO-40°C to +125°C W 8-SOIC MAX14879AWE+ 2.75YES-40°C to +125°C W 16-SOIC MAX14879AWE+T 2.75YES-40°C to +125°C W 16-SOIC MAX14880AWE+5YES-40°C to +125°C W 16-SOIC MAX14880AWE+T5YES-40°C to +125°C W 16-SOICRevision HistoryREVISION NUMBER REVISIONDATEDESCRIPTIONPAGESCHANGED06/17Initial release—18/17Updated parameters in Electrical Characteristics table and added Typical Operating Circuit7, 14 210/17Corrected the Pin Description section for internally connected pins; updated Figure 29, 12 33/18Updated the Safety Regulatory Approvals section1 46/18Updated Pin Description table1253/19Updated the General Description, Benefits and Features, Package Information, Electrical Characteristics, Pin Configuration, and Pin Description to add a Wide 8-Pin SOIC package;added MAX14878AWA+ and MAX14878AWA+T to the Ordering Information table1, 3, 8,12, 1465/19Updated the General Description, Benefits and Features, Safety Regulatory Approvals,Electrical Characteristics–Package Insulation and Safety Related Specifications: W 8-SOIC, Electrical Characteristics–Insulation Characteristics (As Defined by VDE 0884-10): W16-SOIC, Electrical Characteristics–Insulation Characteristics: W 8-SOIC, and OrderingInformation sections1–16709/20Updated the General Description, Absolute Maximum Ratings, Package Information,Electrical Characteristics–Package Insulation and Safety Related Specifications: W 8-SOIC,Electrical Characteristics–Insulation Characteristics: W 8-SOIC, and Ordering Informationsections1, 3, 8-9,19For pricing, delivery, and ordering information, please visit Maxim Integrated’s online storefront at https:///en/storefront/storefront.html.

MAX266中文数据手册

MAX266中文数据手册MAX266/265中文数据手册By Hi_Cracker @whu引脚电阻可编程通用高效滤波器-----MAX266/265General Description和MAX265是高效的容滤波器，专门设计用于需要高精度滤波的应用MAX266场合。

内置了两个独立的滤波模块，可以配置成低通，高通，带通，带阻，全通滤波器。

中心频率或者截止频率的控制需要外接电阻以及6 Pin-Strapped 的输入特性来编程实现，然而，Q值仅用电阻连接实现。

各种各样类型的滤波器都可以实现（巴特沃斯，切比雪夫，椭圆滤波器等等）。

内部集成了两个运算放大器。

MAX265可以将中心/截止频率可以最高调到40Khz，然而，MAX266，通过使用一个低范围的fclk/fo比例系数，可以将fos 调到140Khz。

4MHZ系统时钟，可以通过一个晶振或是额外的源获得。

滤波器的操作电压为从±2.37v到±6.3v或者+5V的单电源供电。

Application：声纳电子设备Anti-Aliasing 滤波器数字信号处理震动音频分析远程通信测试仪器Features滤波器参数设置软件化256bit的频率控制字电阻调整Q值和fo140Khz频率调节范围±5V或者单电源﹢5V操作电压Introduction每个MAX266/265都包含的两个可配置滤波器模块已经显示在数据手册前面的功能框图上。

fclk/fo编程输入（F0-F5）被两个滤波模块共用,然而，每个部分的fo仍然受到各自外接电阻的独立调节。

各个模块的的Q值也是受到各自的外接电阻的独立调节的。

MAX266使用比MAX265更低范围的取样比率（fclk/fo），这样就可以产生更高的信号带宽以及fo的可编程范围。

降低fclk/fo产生的影响主要就是比MAX265的滤波器参数的连续性稍微差了一些，但是这些不同可以通过使用图23所示的图形或是美信得滤波器软件来补偿。

265ksps, +3V, 6-/2-Channel, 12-Bit ADCs with +2.5V Reference and Parallel Interface
General
The MAX1265/MAX1267 low-power, 12-bit analog-todigital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed 12-bit parallel interface. They operate with a single +2.7V to +3.6V analog supply. Power consumption is only 5.4mW at the maximum sampling rate of 265ksps. Two software-selectable power-down modes enable the MAX1265/MAX1267 to be shut down between conversions; accessing the parallel interface returns them to normal operation. Powering down between conversions can reduce supply current below 10µA at lower sampling rates. Both devices offer software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation. In single-ended mode, the MAX1265 has six input channels and the MAX1267 has two (three input channels and one input channel, respectively, when in pseudo-differential mode). Excellent dynamic performance and low power, combined with ease of use and small package size, make these converters ideal for battery-powered and dataacquisition applications or for other circuits with demanding power-consumption and space requirements. The MAX1265 is offered in a 28-pin QSOP package, while the MAX1267 comes in a 24-pin QSOP.
