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 8Ω 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.
