PIN NAME

DESCRIPTION

1

VDD

Positive supply. Connect this pin to a clean 2.5V to 3.3V supply.

2

GND

Ground pin. The thermal pad is connected to the GND pin.

3

REXT

External resistor pin is for the ADC reference current, the integration time adjustment

in internal timing mode, and lux range/resolution adjustment. 100k

Ω 1% tolerance

resistor recommended.

4

PD

Power-down pin. This pin is active-high. Applying a logic “high” to this pin will put the

device into power down mode.
