Description	Class G Headphone Amplifier
Datasheet	LM48824_NationalSemiconductorCorporation.pdf

The LM48824 is a Class G, ground-referenced stereo headphone amplifier designed for portable devices.

National’s ground-referenced architecture, which eliminates the large DC blocking capacitors required by traditional headphone amplifiers, saving board space and minimizing system cost. The LM48824 takes advantage of National’s patent-pending Class G architecture offering power savings compared to a traditional Class AB headphone amplifier. Additionally, output noise is improved by common-mode sensing that corrects for any differences between the amplifier ground and the potential at the headpho.
