Analog Devices AD8325 Datasheet
The AD8325 is a 5 V supply operation device designed to support the DOCSIS standard for reverse path transmission. It features an 8-bit serial word interface that determines output gain over a range of 59.45 dB in steps of 0.75 dB. The device includes a low noise fixed gain buffer, a digitally controlled variable attenuator, and a low distortion high power amplifier.
