Gain Control Pin. This controls whether the output range from the DAC is 0-V
REF
or 0-2 V
REF
.
Buffer Control Pin. This pin controls whether the reference input to the DAC is buffered or unbuffered.
Reference Input for DAC B.
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.
No Connect.
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.
Address pin for selecting between DAC A and DAC B.
Asynchronous active low control input that clears all input registers and DAC registers to zeros.
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. These parts can operate from 2.5 V to 5.5 V and the supply should be decoupled with a
10 F capacitor in parallel with a 0.1 F capacitor to GND.
12 Parallel Data Inputs. DB
