Mnemonic
Description
1
DB8
Parallel Data Input.
2
DB9
Most Significant Bit of Parallel Data Input.
3
VREF
Unbuffered Reference Input.
4
VOUT
Output of DAC. Buffered output with rail-to-rail operation.
5
GND
Ground reference point for all circuitry on the part.
6
CS
Active Low Chip Select Input. This is used in conjunction with WR to write data to the parallel interface.
7
WR
Active Low Write Input. This is used in conjunction with CS to write data to the parallel interface.
8
GAIN
Gain Control Pin. This controls whether the output range from the DAC is 0 V to VREF or 0 V to 2 × VREF.
9
CLR
Active low control input that clears all input registers and DAC registers to zero.
10
LDAC
Active low control input that updates the DAC registers with the contents of the input registers.
11
PD
Power-Down Pin. This active low control pin puts the DAC into power-down mode.
12
VDD
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.
13 to 20
DB0 to DB7
Eight Parallel Data Inputs.
