LM4802BLQ/NOPB Datasheet PDF - TI

●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 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.

●The LM4802B is unity-gain stable. Its gain is set by external resistors.
