AD52661-15W Stereo Class-D Audio Amplifier With Power Limit and Dynamic Range Control 停产
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 8W 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.
