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 AD5551/AD5552 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!

.
This is an active low-logic input signal. The chip select signal is used to frame the serial
data input.
Clock Input. Data is clocked into the input register on the rising edge of SCLK. Duty cycle
must be between 40% and 60%.
Serial Data Input. This device accepts 14-bit words. Data is clocked into the input register on
the rising edge of SCLK.
Digital Ground. Ground reference for digital circuitry.
