Hello,
I need to estimate precisely the consumption of the PPG sensor as our project will be "power consumption critical".
I have some question concerning the datasheet, could you please help me?
- I can read TX_ANA_SUP = 700uA and RX_DIG_SUP = 270uA. If I understand right, both will consumes power all the time, and it doesn't take into account the LED consumption?
-Then I read LED_DRV_SUP = 55uA and TX_CRTL_SUP = 15uA. If I want to estimate the average current consumption, do I need to do : TX_ANA_SUP + RX_DIG_SUP + LED_DRV_SUP (only when led are exposed) + TX_CTRL_SUP + Average LED current (chosen by myself) ?
Thank you,
Best Regards,
Aurelie Duval
