16.0 ANALOG-TO-DIGITAL

CONVERTER (ADC) MODULE

The Analog-to-Digital Converter (ADC) allows

conversion of an analog input signal to a 10-bit binary

representation of that signal. This device uses analog

inputs, which are multiplexed into a single sample and

hold circuit. The output of the sample and hold is

connected to the input of the converter. The converter

generates a 10-bit binary result via successive

approximation and stores the conversion result into the

ADC result registers (ADRESH:ADRESL register pair).

Figure 16-1 shows the block diagram of the ADC.

The ADC voltage reference is software selectable to be

either internally generated or externally supplied.

The ADC can generate an interrupt upon completion of

a conversion. This interrupt can be used to wake-up the

device from Sleep.
