It delivers 1.35W into an 8Ω speaker load and 25mW per channel into 32Ω headphones — enough for portable speakers, docking stations, or panel-mount audio on industrial equipment. ## Integrated features cut external BOM count On-chip features include an I²C-controlled volume, an input multiplexer, depop circuitry to suppress click-and-pop on startup, and a shutdown pin — all of which reduce the number of external passives and GPIOs needed. The supply voltage range of 2.7V to 5.5V lets it run directly from a single Li-ion cell or a 5V USB rail without an extra regulator. Differential inputs improve noise rejection in electrically noisy environments like motor drives or switch-mode power supplies nearby. ## Active production — no LTB pressure The NOPB suffix indicates lead-free / RoHS-compliant finish, which is the standard for new builds. ## 25-BGA layout and rework considerations The 25-WFBGA package with a 2.01x2.01 mm body demands a fine-pitch stencil and controlled reflow profile — typical for a 0.4 mm or 0.5 mm ball pitch. Surface-mount assembly with no exposed thermal pad means the primary heat path is through the solder balls to the PCB copper planes; a 2-layer board with solid ground pours under the BGA is sufficient for the 1.35W output.","metaTitle":"LM49153TME/NOPB Texas Instruments Boomer Audio Subsystem –","metaDescription":"Texas Instruments LM49153TME/NOPB mono audio subsystem with Class D/Class G amp, 1.35W into 8Ω, I²C volume control, industrial temp range, 25-BGA.","metaKeywords":null},"attributes":{"series":"Boomer®, PowerWise®","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"Class D, Class G","Series":"Boomer®, PowerWise®","Package":"Bulk","Features":"Depop, Differential Inputs, I²C, Input Multiplexer, Shutdown, Volume Control","Output Type":"1-Channel (Mono) with Mono and 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":"1.35W x 1 @ 8Ohm; 25mW x 2 @ 32Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.86","stockQuantity":0,"priceTiers":[{"qty":105,"price":"$2.86000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/12df04cb8c0c82531b60331e6ec62117.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output power of the LM49153TME/NOPB?","answer":"The speaker channel delivers 1.35W into 8Ω, and the headphone outputs deliver 25mW per channel into 32Ω."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM49153TME-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/LM49153TME-NOPB when reusing this data.
