*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
specification is not implied. Exposure to the above maximum rating conditions for
extended periods may affect device reliability.

Function
Load Strobe. Transfers shift register
data to DAC register while active low.
See truth table for operation.
Clock Input. Positive edge clocks data
into shift register.
Serial Data Input. Data loads directly
into the shift register.
Resets DAC register to zero condition.
Active low input.
Analog and Digital Ground.
DAC Voltage Output. Full-scale output
1 LSB less than reference input voltage REF.
Positive Power Supply Input. Specified
range of operation 2.7 V to 5.5 V.
DAC Reference Input Pin. Establishes
DAC full-scale voltage.

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 AD7390/AD7391 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!
