Description
DAC Reference Voltage Input Pin.
DAC Feedback Resistor Pin. This pin establishes voltage output for the DAC by
connecting to an external amplifier output.
DAC Current Output.
Ground Pin.
Load Strobe, Level-Sensitive Digital Input. Transfers shift-register data to DAC register
while active low.
12-Bit Serial Register Input. Data loads directly into the shift register MSB first. Extra
leading bits are ignored.
Serial Clock Input. Positive-edge clocks data into shift register.
Positive Power Supply Input.
Do Not Connect to These Pins.
