No effect
Shift register data transferred to DAC register
Description
Clock Input. Positive-edge triggered, clocks data into shift register.
Serial Register Input. Data loads directly into the shift register MSB first. Extra leading bits are ignored.
Internal Matching Feedback Resistor. This pin connects to an external op amp for voltage output.
DAC Reference Input Pin. Establishes DAC full-scale voltage. Constant input resistance vs. code.
DAC Current Output. This pin connects to the inverting terminal of the external precision I-to-V op amp for
voltage output.
Analog and Digital Ground.
Positive Power Supply Input. Specified range of operation at 5 V ± 10%.
Chip Select. Active low digital input. Transfers shift-register data to DAC register on rising edge.
See Table 4 for operation.
