AD52080-3W Stereo Class-D Audio Amplifier with Headphone Driver
DataSheetDescription
The AD52080 is a stereo, filter-less Class-D audio amplifier with a Class-AB headphone driver also. Operating with 3.0V~5.8V wide power supply range, it delivers 3W/CH power into 4? loudspeaker within 10% THD+N or 80mW/CH power into 32? headphone within 1% THD+N
The AD52080 has not only a 64-step DC volume controller, also with a 2.5W power limiter, which implement with an automatic gain controller (AGC) internally.
The AD52080 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 application.
