Part Number	LM48822 Datasheet
Manufacturer	National Semiconductor
Overview	The LM48822 is a single supply, ground-referenced stereo headphone amplifier designed for portable devices, such as cell phones, where board space is at a premium. The LM48822 features National’s grou. National’s ground-referenced architecture, which eliminates the large DC blocking capacitor required by traditional headphone amplifiers, saving board space and minimizing system cost. The LM48822 features common-mode sensing that corrects for any differences between the amplifier ground and the pot.
