NAME
DESCRIPTION
1
CLK
Clock input, positive edge triggered clocks data into shift register
2
SDI
Serial register input, data loads directly into the shift register MSB first. Extra leading bits are ignored.
3
RFB
Internal matching feedback resistor. Connect to external op amp output.
4
VREF
DAC reference input pin. Establishes DAC full-scale voltage. Constant input resistance versus code.
5
IOUT
DAC current output. Connects to inverting terminal of external precision I to V op amp.
6
GND
Analog and digital ground
7
VDD
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
8
CS
operation.
