Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM48861 PowerWise® Ground-Referenced, Ultra Low Noise, Stereo Headphone Amplifier LM48861 March 16, 2010 Ground-Referenced, Ultra Low Noise, Stereo Headphone.

General Description

The LM48861 is a single supply, ground-referenced stereo headphone amplifier.

Part of National's PowerWise® product family, the LM48861 consumes only 3mW of power, yet still provides great audio performance.

The ground-referenced architecture eliminates the larger DC blocking capacitors required by traditional headphone amplifier's saving board space and reducing cost.

Key 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 LM48861 delivers 22mW/channel into a 32Ω load with.
