The LM4805 is a boosted audio power amplifier designed for driving 8ohm speakers in portable applications. It delivers at least 1W continuous power to an 8 load from any input voltage between 3V and 4.6V with less than 2% THD+N.
Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4805 does not require bootstrap capacitors, or snubber circuits. Therefore it is ideally suited for portable applications requiring high power and minimal size.
The LM4805 features a low-power consumption shutdown mode along with an internal thermal shutdown protection mechanism and short circuit protection.
The LM4805 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions
