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. Connect to external op amp output.
DAC reference input pin. Establishes DAC full-scale voltage. Constant input resistance
versus code.
DAC current output. Connects to inverting terminal of external precision I to V op amp.
Analog and digital ground
Posiitve power supply input. Specified range of operation 2.7 V to 5.5 V.
Chip select, active low digital input. Transfers shift register data to DAC register on
rising edge. See Table 1 for operation.
