The AD83281 is a low cost amplifier designed for coaxial line driving. The features and specifications make the AD8328 ideally suited for MCNS-DOCSIS and EuroDOCSIS applications. 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.
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.
Distortion performance of −53 dBc is achieved with an output level up to 60 dBmV at 65 MHz bandwidth over a wide temperature 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 and a 20-lead QSOP. The AD8328 operates from a single 5 V supply and has an operational temperature range of −40°C to +85°C.
