I'm try to figure what the offset voltage temp drift for the Ina116P op-amp,
Ina116P datasheet:
At the bottom left side of page 5 is a chart. Looks like there's an appreciable chance of getting an op-amp that near 20uV/C drift! I would like to build an electrometer that has extremely low input bias current and low drift, but that kind of drift seems far to much. If it's 20uV/C and a gain of 1000 then it's 20mV drift per C, correct? I'm more used to op-amps like the AD8551, which has a typical drift of
0.005uV/C.AD8551 datasheet:
I appreciate any help or advice. Paul
