10-bit A/D converter (ADC)

10.3.1

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 5

multiplexed analog input channels (refer to device pin out description) that allow the

peripheral to convert the analog voltage levels from up to 5 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.

Functional description

Analog power supply

VDDA and VSSA are the high and low level reference voltage pins. In some devices (refer to

device pin out description) they are internally connected to the VDD and VSS pins.

Conversion accuracy may therefore be impacted by voltage drops and noise in the event of

heavily loaded or badly decoupled power supply lines.
