NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and
NiPdAu plate - e4 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

PIN NUMBER PIN NAME
DESCRIPTION
1
VDDD Positive digital supply: 2.25V to 3.63V.
2
VDDA Positive analog supply: 2.25V to 3.63V, VDDA and VDDD should be externally shorted.
3
GND Ground. The thermal pad is also connected to the GND pin.
4
REXT External resistor pin setting the internal reference current and the conversion time. 499kΩ with 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 V_DD, 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.
