how to reconcile the capacitive sensor with a close differential amplifier?

ADA4938 or ADA4939  in the band 0=500mHz  C=some Pf

  • Hi Dmitrii,

    Questions:

    1. Is your sensor in IC form, is it a voltage output device? If yes:

    2. What is its output impedance? High or low? If it has a high output impedance, use ADA4817-2, the first amplifier buffer configured and the other one with gain. If low output impedance, use ADA4927.

    Regards.
