5.3 Digital-to-Analog Converter (DAC)

The Microchip AVR family of devices do not offer an integrated Digital-to-Analog converter (DAC) peripheral, but when migrating from AVR family to the MSPM0 family, you can make use of the MSPM0 internal 12-bit DAC to generate analog voltages. The MSPM0 family offers a 12-bit DAC peripheral to perform digital to analog conversion for various applications. In the MSPM0 G-Series 80-MHz Microcontrollers Technical Reference Manual, the MSPM0 series data sheets, and the MSPM0 SDK, the 12-bit DAC peripheral is referred to as the DAC12. This differentiates the DAC12 from the 8-bit DACs that are available for use with each comparator peripheral included in a given MSPM0 device. Those additional 8-bit DACs are covered in the comparator section of this document. This DAC12 peripheral is only available on the MSPM0G family of devices.

The features of the 12-bit DAC peripherals for the MSPM0G are summarized in Table 5-4.
