Description
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.
