D类低功率音频放大器
AD52656-ST24NAR
The AD52656 is a stereo, filter-less class-D audio amplifier with 2.5W power limit and class-AB headphone driver. Operating with 5.0V power supply, it delivers 2.45W/CH power into 4Ω loudspeaker within 1% THD+N or 65mW/CH power into 32Ω headphone within 1% THD+N
The AD52656 has not only a 64-step DC volume controller, but also a 2.5W power limiter, which implement with an automatic gain controller (AGC).
The AD52656 is packaged as SSOP-24(150mil) 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.
