Hi there,
I have a question about AD620's Table 4.
http://www.analog.com/static/imported-files/data_sheets/AD620.pdf
About the Homebrew circut caluculation, where does Gain Nonliniarity spec"40ppm" come from?
I checked OP07D datasheet, but it does not look like the datasheet mention this spec.
Best regards,
Tarzan
