Description
The AD52653 is a stereo, filter-less class-D audio
amplifier and has a 64-steps DC volume control.
Operating with 5.0V loudspeaker driver supply, it
delivers 2.6W/CH power into 4 loudspeaker within
10% THD+N.
The AD52653 is a stereo audio amplifier with
high efficiency, which leads to longer battery life,
less heat sink, smaller board size, lower system cost,
and suitable for the notebook, and portable
multimedia devices.
