Pin Descriptions
PIN NUMBER PIN NAME
DESCRIPTION
1 VDDD Positive digital supply: 2.5V to 3.63V.
2 VDDA Positive analog supply: 2.5V to 3.63V, VDDA and VDDD should be externally shorted.
3 GND Ground.
4 REXT External resistor pin setting the internal reference current and the conversion time. 499kwith 1% tolerance resistor
is recommended.
5 SCL I2C serial clock line
6 SDA I2C serial data line
The I2C bus lines can be pulled from 1.7V to above VDD, 3.63V max.
7 INT Interrupt pin; LO for interrupt/alarming. The INT pin is an open drain.
8 IRDR IR LED driver pin connecting to the anode of the external IR LED. The source current of the IR LED driver can be
programmed through I2C.
Exposed pad connected to ground or electrically isolated.
