GENERAL DESCRIPTION
The AD8324
1
is a low cost amplifier designed for coaxial line
driving. The features and specifications make the AD8324
ideally suited for DOCSIS 2.0 and Euro-DOCSIS applications.
The gain of the AD8324 is digitally controlled. An 8-bit serial
word determines the desired output gain over a 59 dB range,
resulting in gain changes of 1 dB/LSB.
The AD8324 accepts a differential or single-ended input signal.
The output is specified for driving a 75 Ω load through a 1:1
transformer.
Distortion performance of –54 dBc is achieved with an output
level up to 61 dBmV at 65 MHz bandwidth.
This device has a sleep mode function that reduces the quies-
cent current to 30 µA and a full power-down function that
reduces power-down current to 2.5 mA.
The AD8324 is packaged in a low cost 20-lead LFCSP package
and a 20-lead QSOP package. The AD8324 operates from a
single 3.3 V supply.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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.
ESD 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 this product 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.
