Pin No. Mnemonic Descriptions

1

VREF

DAC Reference Input Pin. Establishes DAC full-scale voltage. Constant input resistance vs. code.

2

RFB

Internal Matching Feedback Resistor. Connect to external op amp output.

3

IOUT

DAC Current Output, full-scale output 1 LSB less than reference input voltage −VREF.

4

GND

Analog and Digital Ground.

5

LD

Load Strobe, Level-Sensitive Digital Input. Transfers shift-register data to DAC register while active low.

See Table 4 for operation.

6

SRI

12-Bit Serial Register Input, data loads directly into the shift register MSB first. Extra leading bits are ignored.

7

CLK

Clock Input, positive-edge clocks data into shift register.

8

VDD

Positive Power Supply Input. Specified range of operation 5 V ± 10%.
