Hi there,

Looking for an isolated ADC to read hall sensor while isolating it from MCU. Is there any IC or a certain topology that can do this function ?

Regards,

 

Too little information.

Exactly what needs to be isolated from what? Why do you need isolation?

I am reading the hall sensor of a brushless DC motor for a F28399D board (C2000) in a try to isolate c2000 totally from the high voltage system

 

TI makes some digital isolators with power good for 5KV of isolation.

Just the first one I found, AFAIK these are common these days.

A simple diagram would help narrow down the choices.

Nice, but I would expect this project to need some power to the sensor too, hence I would start looking at something like this.
