PIC10(L)F320/322
15.0 ANALOG-TO-DIGITAL
CONVERTER (ADC) MODULE
The Analog-to-Digital Converter (ADC) converts an
analog input signal to an 8-bit binary representation of
that signal. This device uses three analog input
channels, 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 an 8-bit binary result via successive
approximation and stores the conversion result into the
ADC result register (ADRES). Figure 15-1 shows the
block diagram of the ADC.
The ADC voltage reference is software selectable to be
internally generated.
The ADC can generate an interrupt upon completion of
a conversion. This interrupt can be used to wake-up the
device from Sleep.
