Description:

Audio Power Amplifier

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 stabl

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 bo
