The Analog Quad offers a wide variety of prescaling options to enable the ADC to resolve the input
signals.
conversion. The ADC internal reference voltage and the prescaler factors were selected to make both
prescaling and postscaling of the signals easy binary calculations (refer to
details). When an analog input pad is configured with a prescaler, there will be a 1 MΩ resistor to ground.
This occurs even when the device is in power-down mode. In low power standby or sleep mode (V

current on V
These scaling factors hold true whether the particular pad is configured to accept a positive or negative
voltage. Note that whereas the AV and AC pads support the same prescaling factors, the AT pad
supports a reduced set of prescaling factors and supports positive voltages only.
