AD52650 - 2.5W/CH Stereo Filter-less Class-D Audio Amplifier

General Description

The AD52650 is a stereo, filter-less class-D audio amplifier.

Operating with 5.0V loudspeaker driver supply, it can deliver 2.5W/CH output power into 4 Ω loudspeaker within 10% THD+N.

The AD52650 has two volume control modes by setting MODE pin.
