• AD637: Pin layout

    The AD637 surface mount package (R) has 2 more pins than the DIP
    (D) and (Q) Packages. Unfortunately the data sheet does not indicate
    where the Power Supply pins are on the surface mount package.
    On the DIP packages -Vs is on pin 10 an…
  • AD637: chip select function - All outputs High Impedance?

    My question relates to the functionality of the chip select function. When CS
    is tied to a low voltage (less than 0.2V) the datasheet indicates that the
    output goes to high impedance. My question is whether the output of the buffer
    amplifier also…

  • Re: AD637 SPICE model issue with LTspice: Partially solved

    In reference to the closed discussion "https://ez.analog.com/amplifiers/f/q-a/15263/ad637-spice-model-issue-with-ltspice", I also had this issue recently and was able to make the AD637 simulation run with the following limitations: 1. The input has to…

  • Which type of capacitor can be used for CAV?CF1?CF2 in the EVB of AD637

    Which type of capacitor can be used for CAV?CF1?CF2 in the EVB of AD637

     

    I used solid tantalum capacitors, but film types are better down to certain
    frequencies. Tantalum styles are less expensive, film types have much less
    leakage, which can…

  • The advantage or special consideration of using dB output instead of the RMS output of AD637

    What is the advantage or special consideration of using dB output instead of
    the RMS output of AD637

     

    The dB feature provides a log conversion of the input voltage such as typically
    used by audio sound-level instruments, or other things such as…

  • RE: AD637 max output current

    Hi,

    Basing from the output characteristics of 13.5V at RL = 2kOhms, this will give an I = 6.75mA.
    The 6mA from the table I would say that the amplifier operates on linear condition and expect your output current will not be greater than your short circuit…

  • 关于AD637在orcad仿真中的使用问题

    使用Ad637的Pspice模型在orcad capture cis的仿真过程中,搭建了一个最简单的测试电路,但是一直报收敛问题,忽视后输出的结果也完全不对。卡住很久了,希望有人路过能指导一下。

  • about the Input dynamic range of AD637

    I will get the RMS value of the signal as below with AD637.

    But I doubt that the long time duration of the small voltage level would be increase the error of the RMS value.

    So, I want to know it's a correct choice for AD637 in my design.
