DAC - Digital to Analog Converter
Description
Digital to Analog Converter (DAC) Peripheral API.
This module contains functions to control the DAC peripheral of Silicon Labs 32-bit MCUs and SoCs. The DAC converts digital values to analog signals at up to 500 ksps with 12-bit accuracy. The DAC is designed for low-energy consumption and can also provide very good performance.
