1

VDD

Power Supply Input. These parts can be operated from 2.5 V to 5.5 V, and the supply should be decoupled to GND.

2

VOUTA

Buffered Analog Output Voltage from DAC A. The output amplifier has rail-to-rail operation.

3

VOUTB

Buffered Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation.

4

REFIN

Reference Input Pin for the Two DACs. It has an input range from 0.25 V to VDD.

5

GND

Ground Reference Point for All Circuitry on the Parts.

6

SDA

Serial Data Line. This is used in conjunction with the SCL line to clock data into or out of the 16-bit input shift

register. It is a bidirectional open-drain data line that should be pulled to the supply with an external pull-up

resistor.

7

SCL

Serial Clock Line. This is used in conjunction with the SDA line to clock data into or out of the 16-bit input shift

register. Clock rates of up to 400 kbps can be accommodated in the 2-wire interface.

8

A0

Address Input. Sets the least significant bit of the 7-bit slave address.
