Hello.
I am looking for an OP / Precision rectifier which to operate with input voltage of a 1 mV AC ( in the range of 1 to 1kH ) ( if not available such - then the closest as the best ) to about 100 mV, and output suitable for detecting from some 16+ bit ADC. ( probably in the range 500 mV - 5V or alike ).
The input as well can provide very tiny amount of current ( like a few up to tens of nA ).
Any information and guidances is helpful. :)
