Description
DAC Reference Input Pin. Establishes DAC full-scale voltage. Constant input resistance vs. code.
Internal Matching Feedback Resistor. Connect to external op amp output.
DAC Current Output, full-scale output 1 LSB less than reference input voltage −V
Analog and Digital Ground.
Load Strobe, Level-Sensitive Digital Input. Transfers shift-register data to DAC register while active low.
See Table 3 for operation.
12-Bit Serial Register Input. Data loads directly into the shift register MSB first. Extra leading bits are ignored.
Clock Input. Positive-edge clocks data into shift register.
Positive Power Supply Input. Specified range of operation 5 V ± 10%.
Exposed Pad. The exposed pad should be connected to the ground plane.
