GENERAL DESCRIPTION  
The AD8328 is a low cost amplifier designed for coaxial line  
driving. The features and specifications make the AD8328  
ideally suited for MCNS-DOCSIS and Euro-DOCSIS applica-  
tions. The gain of the AD8328 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.

THIRD HARMONIC  
The AD8328 accepts a differential or single-ended input signal. The  
output is specified for driving a 75 Ω load through a 2:1 transformer.

SECOND HARMONIC  
Distortion performance of –53 dBc is achieved with an output  
level up to 60 dBmV at 65 MHz bandwidth over a wide tempera-  
ture range.  
This device has a sleep mode function that reduces the quiescent  
current to 2.6 mA and a full power-down function that reduces  
power-down current to 20 µA.

The AD8328 is packaged in a low cost 20-lead LFCSP package  
and a 20-lead QSOP package. The AD8328 operates from a single  
5 V supply and has an operational temperature range of –40°C  
to +85°C.
