AD62556-LG48NAY
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).
