      Goodafternoon, I wish to know maximum current for DAC P21 and P22, in case of 1.5V output.
      For the project I have actually, I need 100 mA, at least.
      Kind regards.

        @MisureMeccaniche According to the ESP32 data sheet, the maximum drive capacity of a digital output is 40mA for a high level and 28mA for the low level. I expect the analog output of the DAC to drive less. For 100mA and more you will need an amplifier.
