Description
The AD52661 is a high efficiency stereo class-D
audio amplifier with adjustable power limit function
and dynamic range control function. The
loudspeaker driver operates from 8~16.5V supply
voltage and analog circuit operates at 3.3V supply
voltage. It can deliver 15W/CH output power into 8Ω
loudspeaker within 10% THD+N and without
external heat sink when playing music.
AD52661 provides adjustable power limit function
allows user to set a voltage rail by two resister
divider to limit the amount of current through the
speaker. AD52661 also features non-clip function
and DRC (Dynamic Range Control) function that
were developed for low distortion with audio quality.
AD52661 has output DC detection prevents
speaker damage from long-time current stress,
short circuit protection function and over
temperature protection.
