Hi Analog Engineers,
I see in the LT1028 datasheet (as well as in AN-21) that one can use a zero-drift amplifier to offset trim an amplifier. It is stated that this lowers the offset drift: from uV/C to nV/C (which is pretty amazing). I am guessing that this can be done with AD797 as well, only that you reference the negative supply versus the positive supply. Am I correct in assuming this is the way to do it, or that it can even be done with AD797?
