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 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 volume down control, high active Terminal for volume up control, high active Output MUX control.

SM7513 Using stereo line inputs application circuit Page 6 V.1.0 Apr 30,2007 SAMHOP Microelectronics Corp. 3W STEREO AUDIO POWER AMPLIFIER WITH UP / DOWN GAIN CONTROL VOLUME CONTROL The output volume of SM7513 is respectively controlled by two input pins, UP and Down pin. The UP pin controls the volume increment, and the DOWN pin controls the volume decrement. It increases/decreases ±2dB each step. Both are all active high. The SM7513 built-in a RC oscillator and generates a based frequency for volume output register to count increasingly or decreasingly. It starts to count when the UP/DOWN pin is pressed. If the voltage on UP/DOWN pin is disappeared in specific unit period, the volume increment or decrement is not accepted, which means no action, keeps the original voltage and clears the value in count register. Therefore, there is no increment or decrement to make the volume uncertainly. After power on or shutdown, SM7513 will has -4dB±2dB initial gain. The mapping between output volume increment / decrement and active unit period is shown in Figure 2. When the UP Key keeps high for one active unit period, the output gain increases 2db after the Key is released. When the UP Key keeps low and the DOWN Key become high level for one active unit period, the output gain decreases 2db. The action of pressed the UP/DOWN Key continually is shown in Figure 3. The gain is increased/ decreased after one unit periods. If the Key is continually be pressed more than two unit periods, the gain is increased/ decreased until to maximum 20dB or -65dB.
