5.3 Digital-to-Analog Converter (DAC)

The RL78 and MSPM0 family of parts both offer 12-bit, 8-bit DAC peripherals to perform digital to analog conversion for various applications. In RL78 documentation, 12-bit DAC is referred to as the 12-bit D/A converter and 8-bit DAC is referred to as the DAC, D/A Converter. The 12-bit D/A converter is only available on the RL78 I1E and L1A families of devices. In MSPM0, the 12-bit DAC peripheral is referred to as the DAC12. This differentiates the DAC12 from the 8-bits 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 RL78 and MSPM0G are summarized in Table 5-4.
