LM48861 Overview
The LM48861 is a single supply, ground-referenced stereo headphone amplifier. Part of TI'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.
