    • Hi Jino,
    • there is capacitive sensor that gives a signal in the frequency band 0-500mHz. I want to be placed in it close proximity amplifier (ada4927 or ada4817or ada4938 or ada 4939) amplifier with a gain of 1-2 and hand it to an oscilloscope. How do I choose the input circuit of the amplifier for the capacitive sensor several picofarad?
