I have a classic I/V setup with 1 megohm feedback using an ADA4177.
Normally the non-inverting is to ground but I would like to inject my offset bias into this input. Is this an ok approach or is there a better method for this configuration.
I'm only interested in DC current conversion, no bandwidth requirements.
I would tie the + input to gnd with low resistance (<50 ohms) and apply offset voltage direct to + input via a high value resistor.
