GENERAL DESCRIPTION
Advanced up/down volume control minimizes external components and allows BTL (speaker) volume control and SE (earphone) volume control. Wireless headphone 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 up/down gain control to the up/down terminals. FEATURES
* Advanced DC Volume Control With 2-dB Steps From -40 dB to 20 dB * Depop circuitry * Low quiescent current * 1uA shutdown current * 3W into 3Ω from 5.5V supply * Thermal protection * Compact configuration and minimum external components APPLICATIONS
* Mini Speaker * Wireless headphone * Car multimedia system PIN ASSIGNMENTS (TOP VIEW) ROUTN RPVDD RLINEIN VDD LLINEIN LPVDD LOUTN LPGND 1 2 3 4 5 6 7 8 Thermal Pad 16 15 14 13 12 11 10 9 RPGND ROUTP SE/BTL UP DOWN BYPASS SHUTDOWN LOUTP SM7513 16PIN Page 1 V.1.0 Apr 30,2007 SAMHOP Microelectronics Corp. 3W STEREO AUDIO POWER AMPLIFIER...
