I
Device enable pin. EN = logic low = normal operation (default)(1); EN = logic high = low-power mode.
Amplifier ground.
GND

Ambient light cancellation loop enable. IDC_EN = logic low = enable DC cancellation (default)(1)
IDC_EN = logic high = disable DC cancellation.

Positive power supply.
(1) TI recommends driving a digital pin with a low-impedance source rather than leaving the pin floating because fast-moving transients
can couple into the pin and inadvertently change the logic level.
(2) I = input, O = output
