The AD8324 is a low cost amplifier designed for coaxial line driving. The features and specifications make the AD8324 ideally suited for DOCSIS 2.0 and EuroDOCSIS 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 quiescent 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.
