Product details

Class D stereo amplifier with integrated headphone amp and I²C volume control

The LM4949TL/NOPB from TI's Boomer® series is a Class D audio amplifier that drives a 2-channel stereo speaker load at 2.5 W per channel into 4 Ω and a separate stereo headphone output at 190 mW per channel into 16 Ω.

Package and assembly

The 25-bump WFBGA (µSMD) with a 2.7 x 2.7 mm footprint requires a fine-pitch PCB layout and controlled reflow profile. The surface-mount package is suited for automated pick-and-place. No exposed pad is mentioned, so thermal dissipation relies on the board copper and the Class D efficiency.

Frequently asked questions
