How to design an AC voltage value with AD629 to detect about 100 Vp-p with variable frequencies
Can this circcuit do it?
Can you clarify what are you trying to do? Do you want to measure 100V or do you want to have a peak detector or something?
The AD629 is a difference amplifier that measures differential signal and reject large common mode signal.
If you could tell me more about the applications that you are dealing into, I could look for more suitable amplifiers for your circuit.
