Product details

The Texas Instruments LM48861TM is a Class AB stereo headphone amplifier from the Boomer® series, delivering 24mW per channel into a 16 Ω load. The output stage is Class AB, which means it avoids the crossover distortion of Class B while keeping quiescent current lower than a pure Class A design; for a headphone driver the trade-off is acceptable efficiency for clean low-level signal reproduction.

Housed in a 12-bump WFBGA / DSBGA package (supplier device package 12-DSBGA), this part is built for dense, low-profile PCBs.
