ADC problem
PostPosted: Thu Jun 24, 2004 8:41 pm     Reply with quote
Is there anything special with AN0 analog input on PIC16F873A?
I am using three analog inputs AN0, AN1 and AN3. AN1 and AN3 works fine but AN0 is very drifty. Also during RESET the input is drven up to 3.6V. Any suggestion would be very appreciated.

What are the crystal speed, ADC clock settings and the impedance on the AN0 pin?
