Hi Pradeepkumar,

Could you please give some details of the control circuit?

It depends on the drive current or voltage requirements of your circuit.

Best regards,

Wei

Hi Pickle Gao,

Using the DAC to drive a Current control circuit.

Currently have configured the DAC to PA16/A8 of pin no 12. Could you please share your comment on pin no12 configured as DAC current control purpose?

Hi Pradeepkumar,

MSPM0 L-series has no independent DAC module, so we need output COMP.DAC by OPA module. PA16 can be configured as OPA1_OUT, so I think it's OK. You can confirm Pin configuration in the datasheet or SysConfig.

You can refer to the SDK example below:
