Description

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.
