• AD8042: unstable when used as G=+2 buffer

    Q 

    We use Analog DAC-AD5552. We use external Amp (AD8042) for a bipolar output as
    written on the data-sheet (on page 9).
    Without writing ant data we gote 5MHz signal at the bipolar output.
    We use external resistors for bipolar the signal and…

  • Active filter using OP496

    Hi All,

    I designed a butter-worth 4th order filter with Fc = 3.5KHz,

    I wish to use the part OP496GS.

    For verification of the design I acquired the psice model of the part OP196.

    I am using Multisim 10.1 for simulation of my circuit.

    When I am doing…

  • RE: Precision pt100/RTD circuit?

    Hi Chris, thanks for your quick reply.

    I've sketched out something in NI Multisim:

    Description:

    500uA Howland current-source with a ADR425 or similar reference. Could maybe use a matched resistor…

  • OP296 input resistance

    Hi, i would like to know the OP296 input resistance. I was wondering if the OP296 works as a transimpedance amplifier with a 1M feedback resistance (so i need that value). any advice?.


    And the same question for ADA4528.

    Thanks.

  • 使用运算放大器实现直流耦合电池供电电路中的问题

    AN-581_cn.pdf

    参考ADI 应用笔记AN_581《单电源应用中的偏置和去耦运算放大器》设计直流耦合电池供电电路，在P6底部提到电路中 RA,RB电阻阻值的选择需要查看AD663A 数据手册，我查过后发现没有AD663A这款芯片，AD6634/6635/6636是已经停产了的模数转换器，数据手册中也没看到这一部分的内容，这个要怎么解决呢？

    问题2：该电路中，使用了一个跟随器电路，它是起隔离的作用吗？但是为什么反相端和输出端之间连接了一个110k欧姆的电阻呢？

  • how to interface AD5542A dac ic with FPGA memory to provide input data to Din pin of AD5542A?

    Around 256K data is stored as a bunch in memory and we need to convert this digital data to analog at once by applying it to AD5542A dac ic. As chip select need to go low to high after each 16 bit data to latch it to dac.

  • Reference of AD5542A in bipolar mode

    Dear AD engineers,

    Could I ask if +5V/-5V is supported for AD5542A in bipolar mode? It is specified in datasheet everywhere that a 2.5V reference should be used, such as in page 8: Pin REF Connect this pin to an external 2.5 V reference.

    Thanks a lot…
