2. ATmega48V-10MU - (Atmel) My concern is, since I will be using the ADC which is referenced to Vdd, there is a variation of 0.6V (ie., 3.6 - 3.0 ) on the Vdd. On the ATMega the internal bandgap reference can be used as ADC input, so you can use it to correct the deviation of the VCC. Or you insert voltage dividers on the analog inputs and use the bandgap directly as UREF of the ADC. Peter |
