Technical Details & Description

Class AB stereo amplifier in DSBGA

The LM4859TL/NOPB is a Texas Instruments Boomer® series Class AB audio amplifier delivering 1.6W per channel into 4Ω loads from a 2.7V to 5.5V supply. The 2-channel stereo output with dedicated stereo headphone drive covers both speaker and headphone paths from a single 30-ball DSBGA package. Operating across -40°C to 85°C ambient, the part is suited for portable and consumer audio products that must hold performance through temperature extremes — the DSBGA package keeps the footprint small for space-constrained PCBs.

Active production, ROHS3 compliant

The part is ROHS3 compliant, covering the current EU exemption-free material restriction. Sourced to order against BOM quantities; availability and current pricing confirmed at the time of RFQ through independent distribution channels.

Frequently asked questions
