Function
Unbuffered Reference Input for DAC D.
Unbuffered Reference Input for DAC C.
Unbuffered Reference Input for DAC B.
Unbuffered Reference Input for DAC A.
Output of DAC A. Buffered output with rail-to-rail operation.
Output of DAC B. Buffered output with rail-to-rail operation.
Output of DAC C. Buffered output with rail-to-rail operation.
Output of DAC D. Buffered output with rail-to-rail operation.
Ground Reference Point for All Circuitry on the Part.
Active Low Chip Select Input. This is used in conjunction with WR to write data to the parallel interface.
Active Low Write Input. This is used in conjunction with CS to write data to the parallel interface.
LSB Address Pin for Selecting which DAC Is to Be Written to.
MSB Address Pin for Selecting which DAC Is to Be Written to.
Active Low Control Input that Updates the DAC Registers with the Contents of the Input Registers.
This allows all DAC outputs to be simultaneously updated.
Power-Down Pin. This active low control pin puts all DACs into power-down mode.
Power Supply Pin. This part can operate from 2.5 V to 5.5 V and the supply should be decoupled with a
10 µF capacitor in parallel with a 0.1 µF capacitor to GND.
