The Analog-to-Digital converter (A/D) allows conversion
of an analog input signal to a 10-bit binary representation
of that signal. The PIC16F946 has up to eight analog
inputs, multiplexed into one sample and hold circuit. The
output of the sample and hold is connected to the input of
the converter. The converter generates a binary result via
successive approximation and stores the result in a 10-bit
register. The voltage reference used in the conversion is
software selectable to either V
the V
A/D on the PIC16F946.
