Mnemonic
Description
1
V
Power Supply Input. These parts can be operated from 2.5 V to 5.5 V, and the supply should be decoupled to GND.
DD
2
V
A
Buffered Analog Output Voltage from DAC A. The output amplifier has rail-to-rail operation.
OUT
3
V
B
Buffered Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation.
OUT
4
REFIN
Reference Input Pin for the Two DACs. It has an input range from 0.25 V to V
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. SDA 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.
