Name

Function

VDD

VDD Power Supply Connection: VDD range is 2.375V to 5.5V.

CAP

μF connected to ground.

GND

Ground

SHDN

Shutdown: Connect to GND to disable the device. When in shutdown, the part draws no more than 1

μA supply

current and all communications pins (RST, SCL, SDA) are high impedance. Connect to VDD for normal

operation.

RST

Reset: Connect to ground to disable I2C communications.

NC: No connection

SDA(1)

Use 4.7k pullup resistors for I2C communication.

SDA: Serial data I/O line

SCL(1)

I2C Serial Clock Input.
