Description
1
VDD
Positive Power Supply Input. The specified range of operation is 2.7 V to 5.5 V.
2
SHDN
Power Shutdown Active Low Input. DAC register contents are saved as long as power stays on the VDD pin. When
SHDN = 0, CS strobes write new data into the DAC register.
3
CS
Chip Select Latch Enable, Active Low.
4
RS
Asynchronous Active Low Input. Resets the DAC register to 0.
5 to 16
D0 to D11
Parallel Input Data Bits. D11 is the MSB; D0 is the LSB.
17
DGND
Digital Ground.
18
AGND
Analog Ground.
19
VOUT
DAC Voltage Output.
20
VREF
DAC Reference Input. Establishes the DAC full-scale voltage.
