Supply voltage spans 2.7V to 4.5V, matching single-cell Li-ion or 3.3V regulated rails common in portable electronics. ## 12-DSBGA package and board integration Housed in a 12-WFBGA, DSBGA package with supplier device package 12-DSBGA measuring 2x2.5 mm — a compact footprint for space-constrained PCBs in wearables, IoT modules, or portable audio accessories. Surface-mount assembly; the 0.5 mm ball pitch requires standard BGA reflow profiling and X-ray inspection for solder joint verification. ## Sourcing posture for BOM planning No official successor or cross-reference is published; the LM48556TL is the current Boomer series part for this mono Class AB function.","metaTitle":"Texas Instruments LM48556TL Class AB Audio Amp, Mono","metaDescription":"Texas Instruments LM48556TL Boomer Class AB audio amplifier, 1-Channel Mono output, 2.7V-4.5V supply, -40°C to 85°C, 12-DSBGA package.","metaKeywords":null},"attributes":{"series":"Boomer®","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Class AB","Series":"Boomer®","Package":"Bulk","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"12-WFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 4.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"12-DSBGA (2x2.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.85","stockQuantity":0,"priceTiers":[{"qty":163,"price":"$1.85000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aa6ac3f9e6c5a0942f13657995d650cc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output configuration of LM48556TL?","answer":"The LM48556TL provides a 1-Channel (Mono) audio output, suitable for single-speaker or single-headphone applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM48556TL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM48556TL when reusing this data.
