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 AD8327 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.

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.
Logic “0” disables transmission. Logic “1” enables transmission.
Common Positive External Supply Voltage. A 0.1 µF capacitor must decouple each pin.
Common External Ground Reference
Transmit Enable/Disable Timing Capacitor. This pin is decoupled with a 100 pF capacitor to GND.
Output Signal
Internal Bypass. This pin must be externally ac-coupled (0.1 µF capacitor).
Noninverting Input. DC-biased to approximately V
capacitor.
Inverting Input. DC-biased to approximately V
Low Power Sleep Mode. Logic 0 enables Sleep mode, where Z
current is reduced to 5 mA. Logic 1 enables normal operation.
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 simulta-
neously 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.
