SM7513 Datasheet | SamHop Microelectronics

DESCRIPTION The SM7513 is a stereo audio power amplifier that drives 3 W/channel of continuous RMS power into a 3- Ω load. Advanced up/down volume control minimizes external ponents and allows BTL (speaker) volume control and SE (earphone) volume control. Wireless headphone 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 up/down gain control to the up/down terminals. FEATURES - Advanced DC Volume Control With 2-d B Steps From -40 d B to 20 d B - Depop circuitry - Low quiescent current - 1u A shutdown current - 3W into 3Ω from 5.5V supply - Thermal protection - pact configuration and minimum external ponents 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 .Data Sheet.in SAMHOP Microelectronics Corp. 3W STEREO AUDIO POWER AMPLIFIER WITH UP / DOWN GAIN CONTROL PIN ASSIGNMENTS 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 PIN DESCRIPTIONS No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Pin Name ROUTN RPVDD RLINEIN VDD LLINEIN LPVDD LOUTN LPGND LOUTP SHUTDOWN BYPASS DOWN UP SE/BTL ROUTP RPGND I/O O I I O O I I I I I O - Function Right channel negative audio output Supply voltage terminal for power stage Right channel line input Supply voltage terminal Left channel line input Supply voltage terminal for power stage Left channel negative audio output Power ground Left chanel positive audio output Places the amplifier in shutdown mode if a TTL logic low is placed on this terminal Tap to voltage divider for internal midsupply bias generator used for analog reference Terminal for...
