3.10.2 8-bit DAC

8-bit Digital-to-Analog Converter

3.10.2.1 Introduction

The Digital-to-Analog Converter (DAC) supplies a variable voltage reference, ratiometric with the input source, with programmable selectable output levels. The positive and negative input references (VSOURCE+ and VSOURCE-) can each be selected from several sources. The output of the DAC (DACx_output) can be selected as a reference voltage to several other peripherals or routed to output pins.
