*Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; functional operation of the

device at these or any other conditions above those indicated in the operational

sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

PIN FUNCTION DESCRIPTIONS

#(

*)

Name Function

1(7)

DAC Reference Input Pin. Establishes DAC full-

scale voltage. Constant input resistance versus

code.

Internal Matching Feedback Resistor. Connect

to external op amp output.

DAC Current Output, full-scale output 1 LSB

4 (2) GND

Analog and Digital Ground.

5 (3)

LD

Load Strobe, Level-Sensitive Digital Input.

Transfers shift-register data to DAC register

while active low. See truth table for operation.

6 (4) SRI

12-Bit Serial Register Input, data loads directly

into the shift register MSB first. Extra leading

bits are ignored.

7 (5) CLK

Clock Input, positive-edge clocks data into shift

register.

Positive Power Supply Input. Specified range of

operation 5 V

± 10%.

*Note Pin numbers in parenthesis represent the rotated pinout of the

DAC8043A1ES and DAC8043A1FS models.

ORDERING GUIDE

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection.

Although the DAC8043A features proprietary ESD protection circuitry, permanent damage may

occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD

precautions are recommended to avoid performance degradation or loss of functionality.

WARNING!
