AUDIO AMPLIFIER 3W STEREO WITH ADVANCED DC VOLUME CONTROL
DESCRIPTION
The A2232 is a stereo audio power amplifier that drives 3W/channel of continuous RMS power into a 3Ω load. Advanced DC volume control minimizes external ponents and allows BTL (speaker) volume control and SE (headphone) volume control. Notebook and pocket PCs benefit from the integrated feature set that minimizes external ponents without sacrificing functionality. To simplify design, the speaker volume level is adjusted by applying a DC voltage to the VOLUME terminal. Likewise, the delta between speaker volume and headphone volume can be adjusted by applying a DC...
