10-bit A/D converter (ADC) ST72321xx-Auto
172/243 Doc ID 13829 Rev 1
17 10-bit A/D converter (ADC)
17.1 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 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.
17.2 Main features
10-bit conversion
Up to 16 channels with multiplexed input
Linear successive approximation
Data register (DR) which contains the results
Conversion complete status flag
On/off bit (to reduce consumption)
