Our customer found the following matter with your AD8629 OPAMP.
Application is temperature sensor by Thermopile(TP).
Please refer to my enclosed Fig-1 schematic.
In the enclosed schematic, customer replaced TP to fixed resister.175kohm
When power-on, around 90mV appeared at out-1 pin.
Also gained output around 900mV at out-2.
Does your AD8629 have the input offset voltage?
Otherwise why this 90mV appear on output?
Please advice us.
