Hello Team,

Could you please tell me which VCC pin is the power supply for the internal DAC ?

Hi Kawai-san,

I will need to double-check this with design, since it is not explicitly detailed in the datasheet. Please allow a day or two to respond with an answer.

Regards,

Michael

Hi Kawai-san,

I received feedback from design about this part.

The internal DAC is powered by the same pin as the supply for PLL1 (Pin 1).

Thanks,

Michael
