LTC2757 IOUT amplifier

Question

Can we use a zero-drift (chopper stabilized) amplifier like LTC1150 or ADA4523-1 as IOUT amplifier? What should we look out for if we are to use such amplifier?

Hi, 
 The Op Amp Selection section on page 16 of the datasheet outlines the consideration for choosing a suitable I-V opamp for the LTC2757. The main parameters you should check are input offset voltage, input bias current and open loop voltage gain. Zero-drift amplifiers have excellent offset and offset drift parameters. There shouldn't be a problem to use them with the LTC2757.
