Due to the supply problem getting a 3.2, I've moved on to a teensy 4 with a SPI connected DAC (MAX5443). Right now I'm struggling to get it to convert a 440hz sine wave. On the scope it looks like garbage. I'd like to see what others have done to use an external DAC. I want to move up from the 12 bits in the teensy 3.2 dac to 16 bits. Suggestions?
Suggestion for SPI DAC with Teensy 4 (replacing internal DAC on Teensy 3.2)
