Description
High Byte Enable Pin. This pin is used when writing to the device to determine if data is written to the high
byte register or the low byte register.
Buffer Control Pin. This pin controls whether the reference input to the DAC is buffered or unbuffered.
Reference Input.
Output of DAC. 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.
Gain Control Pin. This controls whether the output range from the DAC is 0 V to V
Asynchronous active low control input that clears all input registers and DAC registers to zero.
Active low control input that updates the DAC registers with the contents of the input registers.
Power-Down Pin. This active low control pin puts the DAC into power-down mode.
Power Supply Input. These parts 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.
Eight Parallel Data Inputs. DB
