I am using the ADPD4001 for ECG and PPG measurement, however, for a low-power device, I am using an OLED light source. My OLED works at 100uA maximum. However, the driving current sunk on the ADPD4001 is a minimum of 2mA. Can you advise me on how to lower the current pulled? Would a resistor in series with the OLED work?
I think of a current divider with 2 resistors, but I'm not so sure it would work, and I don't want to burn my OLED on every try.
