Function
Power Supply Input. These parts can be operated from 2.5 V to 5.5 V, and the supply should be decoupled to GND.
Buffered Analog Output Voltage from DAC A. The output amplifier has rail-to-rail operation.
Buffered Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation.
Reference Input Pin for the Two DACs. It has an input range from 0.25 V to V
DD
.
Ground Reference Point for All Circuitry on the Parts.
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.
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.
Address Input. Sets the least significant bit of the 7-bit slave address.
