Active production — Class AB mono amplifier for portable audio
The Texas Instruments LM48556TL is an active-production Class AB audio amplifier from the Boomer series, delivering 1-Channel (Mono) output for speaker or headphone drive in battery-powered designs. 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.
