I
Serial register input; data loads directly into the shift register MSB first. Extra leading bits are
ignored.
O
Internal matching feedback resistor. Connect to external op amp output.
I
DAC reference input pin. Establishes DAC full-scale voltage. Constant input resistance versus
code.
O
DAC current output. Connects to inverting terminal of external precision I/V op amp.
G
Analog and digital ground.
I
Positive power supply input. Specified operating range of 2.7 V to 5.5 V.
I
Chip-select; active low digital input. Transfers shift register data to DAC register on rising edge.
