The 8-DIP (0.300\", 7.62mm) through-hole package is a 100-mil pitch DIP — it fits standard perfboard and sockets, which is why this part still shows up in repair and hobbyist builds.","metaTitle":"LM386N-4 Class AB Audio Amplifier, 1W x 1 @ 8Ω, Obsolete","metaDescription":"Texas Instruments LM386N-4 Class AB audio amplifier, 1W mono output into 8Ω, 5V–18V supply, 8-DIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"Class AB","Series":"-","Package":"Tube","Features":"-","Output Type":"1-Channel (Mono)","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"5V ~ 18V","Base Product Number":"LM386","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"8-PDIP","Max Output Power x Channels @ Load":"1W x 1 @ 32Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1720ed3a06e76d3dde33ca6d9c2533e0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM386N-4/alternatives.json"},"ai":{"faq":[{"question":"Is the LM386N-4 obsolete?","answer":"Yes, Texas Instruments lists the LM386N-4 as Obsolete."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM386N-4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM386N-4 when reusing this data.
