I want to design ADC modul using MCU+ADC chip. There is no problem ADC chip and MCU communication. I want to learn the design of the ADC chip and real word side.

- How can obtain the galvanic isolation between ADC chip and the real word sensor.
- The professional circuits measure current, voltaj , pt100, ohm, etc..with the same circuit. Is there any sample circuit for this type application? or professional circuit shematics.
