Description
AD62556 is a highly integrated USB single
chip for headphone. Many useful features are
programmable with pins or I2C control. The device
also has an I2S input port and I2S output port. The
I2S input port allows other external audio sources to
use the class D amplifier to share the headphone.
The I2S output port allows other high performance
audio device (i.e. AD82586/AD82581B).
