I'm wanting to monitor the voltage of a 2 cell LiPo battery, which will range from 8.4v to about 7v. I was going to use a voltage divider to bring that voltage down to 3.3v, but the range of input voltages would only be 3.3v to 2.75v. Could I bring AGND up to 2v to increase my resolution? Is it a reference voltage in the way that ADC_VREF can be lower than 3.0v?
