That output power is specified at a 9 V supply; drop to 5 V and the available swing halves, so budget the rail voltage against the SPL you need. It is a Class AB amplifier — the output stage biases into conduction across the full waveform, so crossover distortion is low but quiescent current is higher than a pure Class D. For a battery-powered project running off a 9 V cell, the 4 mA typical idle draw is manageable; at 4 V the part still operates, though output headroom shrinks. No last-time-buy window remains open; the part is no longer manufactured. Procurement must source from surplus or broker inventory — the independent channel is the only supply route. Because the part is obsolete, every unit on the market is new-old-stock or pulled from excess. Verify date code freshness and MSL bake requirements before reflow; older stock may have absorbed moisture beyond the rated floor life. ## 8-VSSOP package — reflow profile and board fit The LM386MM-1 comes in an 8-VSSOP (also listed as 8-TSSOP, 8-MSOP) with a 3.00 mm body width. The 0.65 mm pin pitch is standard for this package family; the land pattern matches the JEDEC MO-187 footprint. No exposed pad — thermal dissipation goes through the leads alone. Do not use this part in an engine bay, outdoor enclosure, or any environment that sees sustained temperature outside that window.","metaTitle":"LM386MM-1 Class AB Audio Amp, 325 mW into 8 Ω, Obsolete","metaDescription":"Texas Instruments LM386MM-1 Class AB audio amplifier, 1-channel mono, 325 mW x 1 @ 8 Ω, 4 V to 12 V supply, 0°C to 70°C, 8-VSSOP.","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":"Tape & Reel (TR)","Features":"-","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 12V","Base Product Number":"LM386","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"8-VSSOP","Max Output Power x Channels @ Load":"325mW x 1 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1720ed3a06e76d3dde33ca6d9c2533e0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM386MM-1/alternatives.json"},"ai":{"faq":[{"question":"Can I use the LM386MM-1 in a 5 V circuit?","answer":"Yes. The supply range is 4 V to 12 V, so a 5 V rail is within spec. At 5 V the maximum output power into 8 Ω drops to roughly 125 mW — still adequate for a headphone or small speaker driver."},{"question":"What is the difference between the LM386MM-1 and the LM386N-1?","answer":"The LM386MM-1 is in an 8-VSSOP surface-mount package; the LM386N-1 is in an 8-pin DIP through-hole package. Electrically both are the same Class AB amplifier with identical output power (325 mW into 8 Ω) and supply range (4 V to 12 V). The package is the only difference — the MM-1 is for reflow assembly, the N-1 for through-hole soldering."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM386MM-1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM386MM-1 when reusing this data.
