With adjustable gain from 20× to 200× and output power from 0.25W to 1W depending on supply voltage and load, it's the go-to IC for portable speaker projects, Arduino audio output, intercoms, and battery-powered audio applications. The DIP-8 package makes it ideal for breadboard prototyping.\u003c\/p\u003e\n\n\u003ch3\u003eElectrical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LM386 \/ LM386N \/ LM386N-1 \/ LM386N-3 \/ LM386N-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage:\u003c\/strong\u003e DIP-8 (through-hole, 2.54mm pitch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupply Voltage:\u003c\/strong\u003e 4V – 12V DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Power:\u003c\/strong\u003e 0.25W (4Ω, 6V) \/ 0.5W (8Ω, 9V) \/ 1W (8Ω, 12V, LM386N-4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 20× (default) to 200× (with 10μF between pins 1 and 8)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 50kΩ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuiescent Current:\u003c\/strong\u003e 4mA (typical at 6V)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTHD:\u003c\/strong\u003e 0.2% (typical at 125mW, 8Ω, 6V)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e 0°C to +70°C\u003c\/li\u003e\n  \u003cli\u003eBuilt-in thermal shutdown protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eGain Setting\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e20× (26dB):\u003c\/strong\u003e Pins 1 and 8 open (default)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e50× (34dB):\u003c\/strong\u003e 1.2kΩ resistor between pins 1 and 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e200× (46dB):\u003c\/strong\u003e 10μF capacitor between pins 1 and 8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArduino speaker driver:\u003c\/strong\u003e Drive a small 8Ω speaker from Arduino PWM or DAC output\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePortable speaker:\u003c\/strong\u003e Battery-powered compact speaker amplifier\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntercom system:\u003c\/strong\u003e Voice amplification for two-way communication\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWalkie-talkie audio:\u003c\/strong\u003e Receiver audio amplifier stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAM\/FM radio:\u003c\/strong\u003e Audio output stage for radio receiver circuits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIoT audio alerts:\u003c\/strong\u003e Speaker driver for notification and alarm sounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × LM386 DIP-8 low-voltage audio amplifier IC\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe classic portable audio amplifier IC – the LM386 drives a small speaker directly from 4V–12V with adjustable gain up to 200× and no external power transistors required.\u003c\/p\u003e","brand":"Keszoox","offers":[{"title":"Default Title","offer_id":45674468704491,"sku":"","price":5.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/LM386-Audio-Amplifier-1_c81644d3-22fd-4075-9554-4faedfb832d4.jpg?v=1723007394","url":"https:\/\/keszoox.com\/products\/lm386-low-voltage-audio-amplifier-ic-dip8-0-25w-1w","provider":"Keszoox","version":"1.0","type":"link"}
