• AD737 8k resistor matching

    The AD737 data Sheet mentions that the two 8k resistors inside the AD737 can vary from 6.4k to 9.6k.

    What I couldn't seem to find in the data sheet is how well matched they are to each other.

  • RE: RMS-to-DC for Sound Pressure Level measurement

    Hi Dave,

    I didn't choose any yet. I want to grasp what's going on before ...

    But if it makes it easier, let's say I'll go for the AD737 http://www.analog.com/en/products/linear-products/rms-to-dc-converters/ad737.html

    Thanks !

  • RE: AD737 circuit

    I came to this post because the examples on both the datasheet and applications notes for the AD737 did not work.

    ScottH is right with his circuit proposal. It provides a negative DC signal on the AD737 Output (Pin 6) that is proportional to the RMS…

  • Problem with AD737

    I need to measure pulse current so I bought a few AD737 RMS to DC converters. I
    have a few questions about how to connect the IC. First: My power supply will
    be at 5 V. So what`s the max input voltage?? Second: I`ll measure the current
  • About AD737

    Hi there.

    I have a small question about AD737.

    http://www.analog.com/static/imported-files/data_sheets/AD737.pdf

    This is my first time to use this device.

    So I just wondered if there are any lmitations in case the input signal is a low frequency such…

  • AD737 scale factor and linerity

    Dear all,

    It seems that our measurement and the contents of the data sheet are not in agreement.

    If you may notice, please let me know.

    Q1.

      VR=200ohm is used for Fig.30 in the data sheet (page16)

      What kind of formula is the scale corresponding…
