Please let me change the way of questions about the following case.

Output of AD8436

 

In my circuit has an offset to the output of the RMS-DC.
This offset is a negative voltage.(Therefore, there is a dead zone unlike FIG. 25.)
I've found that offset occurs depending on the leakage current of CAVG.

Please teach me the part number or capacitance and leakage current of CAVG at the time of the following measurement.

Wide dynamic input range: 100 μV rms to 3 V rms

I would like to reference the above.

 

Product shipment is imminent.

Please something of response until 12/2.

 

Thank you.
