Advanced dc volume control minimizes external components and allows BTL (speaker) volume control and SE (headphone) volume control. Notebook and pocket PCs benefit from the integrated feature set that minimizes external components without sacrificing functionality. To simplify design, the speaker volume level is adjusted by applying a dc voltage to the VOLUME terminal. FEATURES * Advanced DC Volume Control With 2-dB Steps From -40 dB to 20 dB - Maximum Volume Setting for SE Mode - Adjustable SE Volume control Referenced to BTL Volume Control * 3 W Into 3-Ω Speakers APPLICATIONS * Notebook PC * LCD Monitors * Portable DVD Player PIN ASSIGNMENTS (TOP VIEW) RLINEIN LLINEIN LOUT- 1 2 3 12 11 10 ROUTROUT+ SE/BTL * Digital photo frame VDD LOUT+ SHUTDOWN 4 5 6 9 8 7 VOLUME GND BYPASS SM7516 HDIP 12PIN Page 1 V.0.1 Sep 12,2007 www.DataSheet.in SAMHOP Microelectronics Corp. 3...
