Housed in an 18-bump WFBGA (supplier device package 18-uSMD, 1.97 x 2.23 mm), this part is a fine-pitch BGA — not a hand-solder job. Rework requires a hot-air station with a nozzle sized to the die, and the board must have a soldermask-defined pad pattern that matches the bump layout. The package is surface-mount only; no through-hole variant exists. Orientation is marked by pin-1 indicator on the substrate — verify it under magnification before placing the part. RoHS compliance is not claimed for this part number (listed as RoHS non-compliant), so it may contain lead in the solder bumps or package finish — factor this into your material declaration and any regional regulatory requirements.","metaTitle":"Texas Instruments LM4855ITL Boomer Audio Amp","metaDescription":"Texas Instruments LM4855ITL Class AB audio amplifier, 1.5W mono into 4Ω plus stereo headphone output.
