Analog Isolation Question
Please connect VINN to GND1 on these amplifiers as per manufacturer recommendation. These chips do get stuck if you go beyond common mode specs due to transient or ESD.


  But the output would be differential? I guess my hang-up is the output and does that work with my micro. The micro is single ended input.


You can draw up a schematic with amplifiers do convert differential to common mode. This will add a lot more uncertainties in your circuit. In offset, (thermal) drift and noise.

Or you use two ADC channels, and subtract in software.



TI also sells a single-ended input isolation amplifier, the AMC1311.
