Connections
On your Devlight/DevFull there are 3 signals to use the Max5821:
- DAC_OUTA: corresponds to OUTA (pin 7) on Max5821. It's the first output.
- DAC_OUTB: corresponds to OUTB (pin 8) on Max5821. It's the 2nd output.
- DAC_REF: corresponds to REF (pin 6) on Max5821. It's the reference voltage (max value that will be achieved by outputs). This input should be connected to a voltage reference between 0 and 3,3V.
