The LM4805 is a boosted audio power amplifier designed fordriving 8ohm speakers in portable applications. It delivers atleast 1W continuous power to an 8Ω load from any inputvoltage between 3V and 4.6V with less than 2% THD+N.Boomer audio power amplifiers were designed specifically toprovide high quality output power with a minimal amount ofexternal components. The LM4805 does not require bootstrapcapacitors, or snubber circuits. Therefore it is ideallysuited for portable applications requiring high power andminimal size.
