I'm using a AD4112 to measure +/-10V differential input voltages. My question is about power for the AD4112. Do I need positive and negative input voltages? Or can I power it with 5V AVDD and 3v3 IOVDD?
The AD4112 does not need positive and negative supplies. It can be powered by a single positive supply
You can use the voltages you mention.
