31.2 Overview

The Digital-to-Analog Converter (DAC) converts a digital value written to the Data register (DAC.DATA) to an analog voltage. The conversion range is between GND and the selected reference voltage.

The DAC features an 8-bit resistor-string type DAC, capable of converting 350,000 samples per second (350 ksps). The DAC uses the internal Voltage Reference (VREF) as the upper limit for conversion. The DAC has one continuous time output with high drive capabilities, which is able to drive 5 kΩ and/or 30 pF load. The DAC conversion can be started from the application by writing to the Data Conversion registers.

This device has three instances of the DAC peripheral, DAC0, DAC1, and DAC2.
