Advanced dc volume control – Maximum Volume Setting for SE Mode minimizes external components and allows BTL – Adjustable SE Volume Control (speaker) volume control and SE (headphone) Referenced to BTL Volume Control volume control. Notebook and pocket PCs benefit from the integrated feature set that minimizes • 3 W Into 3- Ω Speakers external components without sacrificing functionality. • Stereo Input MUX To simplify design, the speaker volume level is • Headphone Mode adjusted by applying a dc voltage to the VOLUME • Pin-to-pin compatible with TPA6011A4 and terminal. Likewise, the delta between speaker volume TPA6012A4 and headphone volume can be adjusted by applying a dc voltage to the SEDIFF terminal. To avoid an • 24-pin PowerPAD™ Package (PWP) unexpected high volume level through the headphones, a third terminal, SEMAX, limits the APPLICATIONS headphone volume level when a dc voltage is • Notebook PC applied. Finally, to ensure a smooth transition • LCD Monitors between active and shutdown modes, a fade mode • Pocket PC ramps the volume up and down. Figure 1.
