ARA2000
Address-Programmable Reverse Amplifier with Step Attenuator

The ARA2000 is designed to provide the reverse path amplification and output level control functions in a CATV Set-Top Box or Cable Modem. It incorporates a digitally controlled precision step attenuator that is preceded by an ultra low noise amplifier stage, and followed by an ultra-linear output driver amplifier.

The ARA2000 has a programmable address that allows multiple devices to share a common control bus. The ARA2000 is offered in a 28-pin SSOP package featuring a heat slug on the bottom of the package.
