Hello ,
I have seen a design with a micro controller having an internal 12 bit ADC.
Here ADC are being used for supply rails monitoring and as well as sensor ( a simple R-divider ) voltage detection.
I'm curious that the designer has connected 2 ADC inputs together to each signal input.
Is this generally used?
Will paralleling multiple ADC input (without any resistors in series ) cause any impedance problems?
Any suggestions is welcome.
Thank you,
