12.0
The Analog-to-Digital converter (A/D) allows conversion
of an analog input signal to a 10-bit binary representation
of that signal. The PIC16F917/916/914/913 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
voltage applied by the V
block diagram of the A/D on the PIC16F917/916/914/913.
