Hi,

 

I need to use Instrumentation amplifier as a precision rectifier and peak detector. My sensor output is really small  halfwave rectified DC or AC voltage of the order 0-5mV and I have high Gain Amplifier AD620 with Gain of 200.

 

Does anyone knows how to use Instrumentation amp as a precision rectifier and peak detector?  Also if possible single supply Instrumentation Amplifier to this job.

Thanks,

 

Chaitanya
