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 + 30 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 components. The LM4802B does not require bootstrap capacitors, or snubber circuits. Therefore it is ideally suited for portable applications requiring high output voltage and minimal size.
The LM4802B features a low-power consumption shutdown mode. Additionally, the LM4802B features an internal thermal shutdown protection mechanism.
The LM4802B contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions
