*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.

Mnemonic Function

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.

Internal Matching Feedback Resistor. Con-

nects to external op amp for voltage 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

for voltage output.

6GND

Analog and Digital Ground

Positive Power Supply Input. Specified range

of operation 5 V

± 10%.

8

CS

Chip Select. Active low digital input. Transfers

shift-register data to DAC register on rising

edge. See Truth Table for operation.

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

AD5543/AD5553 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.
