Description
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.
Buffered Analog Output Voltage from DAC C. The output amplifier has rail-to-rail operation.
Reference Input Pin for All Four DACs. It has an input range from 0.25 V to V
Buffered Analog Output Voltage from DAC D. The output amplifier has rail-to-rail operation.
Ground Reference Point for All Circuitry on the Part.
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 kb/s can be accommodated in the 2-wire interface.
Address Input. Sets the least significant bit of the 7-bit slave address.
