Description
Positive Power Supply Input. The specified range of operation is 2.7 V to 5.5 V.
Power Shutdown Active Low Input. DAC register contents are saved as long as power stays on the V
SHDN = 0, CS strobes write new data into the DAC register.
Chip Select Latch Enable, Active Low.
Asynchronous Active Low Input. Resets the DAC register to 0.
Parallel Input Data Bits. D11 is the MSB; D0 is the LSB.
Digital Ground.
Analog Ground.
DAC Voltage Output.
DAC Reference Input. Establishes the DAC full-scale voltage.
