*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.

Mnemonic
Description
1
SDATA
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.
2
CLK
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.
3
TXEN
Logic “0” disables transmission. Logic “1” enables transmission.
4, 6, 11, 12, 16
VCC
Common Positive External Supply Voltage. A 0.1
F capacitor must decouple each pin.
5, 8, 9, 13, 15
GND
Common External Ground Reference
7
CXR
Transmit Enable/Disable Timing Capacitor. This pin is decoupled with a 100 pF capacitor to GND.
10
VOUT
Output Signal
14
BYP
Internal Bypass. This pin must be externally ac-coupled (0.1
F capacitor).
17
VIN+
Noninverting Input. DC-biased to approximately VCC/2. Should be ac-coupled with a 0.1
F
capacitor.
18
VIN–
Inverting Input. DC-biased to approximately VCC/2. Should be ac-coupled with a 0.1
F capacitor.
19
SLEEP
Low Power Sleep Mode. Logic 0 enables Sleep mode, where ZOUT goes to 200
and supply
current is reduced to 5 mA. Logic 1 enables normal operation.
20
DATEN
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.
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.
