LM4802B Overview
The LM4802B integrates a Boost Converter with an Audio Power Amplifier to drive Ceramic Speakers in portable applications. When powered by a 3V supply, it is capable of forcing 12Vp-p across a 2μF + 30Ω bridge-tied-load (BTL) with less than 1% THD+N. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external ponents.
