General Description
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.
Key Features
- 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 potential at the headphone return terminal, minimizing noise created by any ground mismatches. The LM48822 delivers 35mW/channel into a 16Ω load with.
