Advanced dc volume control minimizes external components and allows BTL – Fade Mode (speaker) volume control and SE (headphone) vol- – Maximum Volume Setting for SE Mode ume control. Notebook and pocket PCs benefit from – Adjustable SE Volume Control the integrated feature set that minimizes external Referenced to BTL Volume Control components without sacrificing functionality. • 3 W Into 3- Ω Speakers To simplify design, the speaker volume level is adjusted by applying a dc voltage to the VOLUME • Stereo Input MUX terminal. Likewise, the delta between speaker volume • Differential Inputs and headphone volume can be adjusted by applying a dc voltage to the SEDIFF terminal. To avoid an unexpected high volume level through the • Notebook PC headphones, a third terminal, SEMAX, limits the • LCD Monitors headphone volume level when a dc voltage is ap- plied. Finally, to ensure a smooth transition between • Pocket PC active and shutdown modes, a fade mode ramps the volume up and down.
