This chip is specifically designed for single supply operations and low external components count. The gain and bias resistors are integrated on-chip, resulting in a 2.5W stereo amplifier in a compact 7-pin\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eTO263\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSMD package. High output power levels at 12V supplies and low external component count offer high value for compact stereo and TV applications. Sufficient power dissipation is provided on PCB so no external heatsink is required for IC.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSupply 12V-16V DC\u003c\/li\u003e\n\u003cli\u003ePO 2.5W Stereo at 10% THD+N @ 1 kHz into 4Ω\u003c\/li\u003e\n\u003cli\u003eDrives 4Ω and 8Ω Loads\u003c\/li\u003e\n\u003cli\u003eInternal Gain Resistors (AV = 34 dB)\u003c\/li\u003e\n\u003cli\u003eMinimum External Component\u003c\/li\u003e\n\u003cli\u003eSingle Supply Operation\u003c\/li\u003e\n\u003cli\u003eInternal Current Limiting\u003c\/li\u003e\n\u003cli\u003eInternal Thermal Protection\u003c\/li\u003e\n\u003cli\u003eOn-Board Power LED\u003c\/li\u003e\n\u003cli\u003eOn-Board Trimmer Potentiometer for Volume Control\u003c\/li\u003e\n\u003cli\u003eScrew Terminal for Power Supply\u003c\/li\u003e\n\u003cli\u003eScrew Terminal for Speaker Connections\u003c\/li\u003e\n\u003cli\u003e3 Pin Male Header for Audio Signal Input\u003c\/li\u003e\n\u003cli\u003eOn-Board Thermal Area for Power Dissipation\u003c\/li\u003e\n\u003cli\u003e4 x 3 mm Mounting Holes\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 75.72 x 89.99mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConnections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN1: Pin 1 VCC, Pin 2 GND\u003c\/li\u003e\n\u003cli\u003eCN2: Audio Signal Input Channel B\u003c\/li\u003e\n\u003cli\u003eCN3: Audio Signal Input Channel A\u003c\/li\u003e\n\u003cli\u003eCN4: Speaker Channel B\u003c\/li\u003e\n\u003cli\u003eCN5: Speaker Channel A\u003c\/li\u003e\n\u003cli\u003ePR1: Trimmer Potentiometer for Channel B Audio Volume Control\u003c\/li\u003e\n\u003cli\u003ePR2: Trimmer Potentiometer for Channel A Audio Volume Control\u003c\/li\u003e\n\u003cli\u003eD1 Power LED\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47036782870700,"sku":"A110","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/A110A.jpg?v=1787567341","url":"https:\/\/dotfry.com\/products\/2-5w-stereo-audio-amplifier-using-lm4752","provider":"dotfry","version":"1.0","type":"link"}
