Interesting! On STM32 etc, the DAC is considered a hacky way of doing audio compared to the SAI peripheral; here without even a DAC, they are making it work.

- nomel 3y agoThey've directly implemented a classic design of a DAC by using an external component. You can buy DACs that are exactly this. You can also implement a DAC with digital IO and some resistors. But, having things integrated is nice, and often cheaper. :)
