Analog-to-digital converter input 15.AnalogIPD010AIN15
This input provides a reference voltage used to
specify the input voltage at which the ADC converts
to a maximum value. In other words, the voltage
that is applied to VREFA is the voltage with which
an AINn signal is converted to 4095. The VREFA
input is limited to the range specified in Table
23-22 on page 993 .
