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 AD8321 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.

Function
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.
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 previ-
ous gain state) and simultaneously enables the register for serial data load.

Common External Ground Reference.

/2 Reference Pin. A dc output reference level that is equal to 1/2 of the supply voltage (VCC). This
port should be externally ac-decoupled (0.1
μ
F capacitor). For external use of this reference voltage,
buffering is required.
Power-Down Low Logic Input. A Logic 0 powers down (shuts off) the power amplifier disabling the
output signal and enabling the reverse amplifier. A Logic 1 enables the output power amplifier and
disables the reverse amplifier.
Common Positive External Supply Voltage.
Output Signal Port. DC-biased to approximately V
