The stereo headphone output is 45mW per channel into 32Ω, typical for consumer earbuds or a local monitoring jack. If your BOM calls for a single audio IC to drive both a speaker and headphones, this part saves a second amplifier and the associated PCB area. ## I²C control and feature set Volume, mute, and shutdown are all set over I²C — no analog pots or GPIOs needed. The differential input path rejects common-mode noise picked up on long traces. Thermal protection and shutdown are built in, so a stalled speaker or shorted output won't cook the die. Depop eliminates the pop on power-up or volume change, which matters in a headphone output where the user hears every transient. ## Package and handling It comes in a 25-ball WFBGA, 2.01 x 2.01 mm — tiny, but that means a stencil and reflow are mandatory. No lab bench swap here; you need a hot-air station or reflow oven. The balls are on a fine pitch, so orientation is critical: the package marking (if present) is your only guide. If you are planning a field-service swap, socketing is impractical at this pitch — plan for board-level rework or a spare populated module.","metaTitle":"LM49101TM/NOPB Class AB Audio Subsystem","metaDescription":"LM49101TM/NOPB Boomer® Class AB audio subsystem: 1.3W mono into 8Ω, 45mW stereo into 32Ω, I²C volume control, 25-BGA, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"Boomer®, PowerWise®","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"Class AB","Series":"Boomer®, PowerWise®","Package":"Bulk","Features":"Depop, Differential Inputs, I²C, Shutdown, Thermal Protection, Volume Control","Output Type":"1-Channel (Mono) with Stereo Headphones","Mounting Type":"Surface Mount","Package / Case":"25-WFBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"25-BGA (2.01x2.01)","Max Output Power x Channels @ Load":"1.3W x 1 @ 8Ohm; 45mW x 2 @ 32Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.22","stockQuantity":0,"priceTiers":[{"qty":136,"price":"$2.22000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/980440944054c10692d0983e8e70d7ca.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum output power of LM49101TM/NOPB?","answer":"The mono speaker channel delivers 1.3W into 8Ω, and the stereo headphone output delivers 45mW per channel into 32Ω."},{"question":"Does LM49101TM/NOPB support I²C volume control?","answer":"Yes, it has a full I²C interface for volume control, mute, and shutdown — no external pots or logic pins needed."},{"question":"What are the typical applications of LM49101TM/NOPB?","answer":"Battery-powered portable devices, industrial control panels with audio alerts, and automotive cabin audio where a single speaker plus headphone jack is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM49101TM-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM49101TM-NOPB when reusing this data.
