Simple amp with volume control

[roadster]

Does anyone know how to make a simple 2W ish amplifier circuit that can have a volume control that is electronic say controlled from a few I/O lines or serial lines. My application is an audio output from a TV tuner that I want to amplify and control via a CPU/Microcontroller.

gain control

Xicor makes a large variety of digitally controlled voltage dividers. This can be used for your gain control. Then use an ordinary audio power amplifier IC. http://www.xicor.com/product_select_guide_ms.php

I think this could be the one: TDA8551 - NF power amplifier with simple volume control, two buttons: up / down.
