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.
