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 AD8322 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.

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
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Description
Serial Data Input. This digital input allows for an 8-bit serial (gain) word to be loaded into the internal
register with the MSB (Most Significant Bit) first.
Clock Input. The clock port controls the serial attenuator data transfer rate to the 8-bit master-slave
register. A Logic 0-to-1 transition latches the data bit and a 1-to-0 transfers the data bit to the slave.
This requires the input serial data word to be valid at or before this clock transition.
Data Enable Low Input. This port controls the 8-bit parallel data latch and shift register. A Logic 0-to-1
transition transfers the latched data to the attenuator core (updates the gain) and simultaneously inhibits
serial data transfer into the register. A 1-to-0 transition inhibits the data latch (holds the previous gain
state) and simultaneously enables the register for serial data load.
Common External Ground Reference.
Internal Bypass. This pin must be externally ac-decoupled (0.1 µF capacitor).
Common Positive External Supply Voltage. A 0.1 µF capacitor must decouple each pin.
Logic “0” powers down the part. Logic “1” powers up the part.
