Hello All,
I am willing to use an ideal TI component for receiving 0-5V ADC input to my 3.3V controller. However, my sensor which provides this 0-5V output is powered from 24V rail.
In my entire circuit I have many components like motors, inductive sensors, infrared sensors etc... in 24V rail. And so far I have maintained Ground isolation between 24V rail and 5V rail entirely to avoid unnecessary noise.
Just this one particular sensor where I need to receive 0-5V ADC input to my 3.3V controller is causing me issue because Sensor is using 24V circuit ground and my controller is using 5V circuit ground.
Is there any circuit that can give me this linear isolation with isolated grounds? Could be a linear opto isolator. I am looking for +/- 10mV accuracy. I can do error offset in software if the error is linear though.
Please help if possible. Thank you.
