Pin No. Mnemonic Description
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
VOUTC
Buffered Analog Output Voltage from DAC C. The output amplifier has rail-to-rail operation.
5
REFIN
Reference Input Pin for All Four DACs. It has an input range from 0.25 V to VDD.
6
VOUTD
Buffered Analog Output Voltage from DAC D. The output amplifier has rail-to-rail operation.
7
GND
Ground Reference Point for All Circuitry on the Part.
8
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.
9
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 kb/s can be accommodated in the 2-wire interface.
10
A0
Address Input. Sets the least significant bit of the 7-bit slave address.
