DESCRIPTION
Positive supply. Connect to a clean 2.25V to 3.3V supply
Ground. The thermal pad is connected to the GND pin
External resistor pin is for the ADC reference current, the integration time adjustment in internal timing
mode, and lux range/resolution adjustment. 100kΩ 1% tolerance resistor recommended.
Bit 0 of the I²C address.
Bit 1 of the I²C address.
Bit 2 of the I²C address.
The address pins have an open gate equivalent circuit. These are the
least-significant bits of the I²C address. The eight possible addresses are
40(hex) through 48(hex).
I²C serial clock line
I²C serial data line
The I²C bus lines can pulled above V_DD, 5.5V max.
