10-bit A/D converter (ADC)
Introduction
The on-chip Analog to Digital Converter (ADC) peripheral is a 10-bit, successive
approximation converter with internal sample and hold circuitry. This peripheral has up to 16
multiplexed analog input channels (refer to device pin out description) that allow the
peripheral to convert the analog voltage levels from up to 16 different sources.
The result of the conversion is stored in a 10-bit data register. The A/D converter is
controlled through a control/status register.
