Description
AD62553 is a highly integrated USB single
chip for Stereo/Mono speaker or headphone.
Many useful features are programmable with
pins or I2C control. When using the power
supplied from the USB port (USB 3.0), AD62553
can drive a pair of up to 2.1W into 4ohm
speakers due to the built-in, high efficiency and
high performance class-D amplifiers. The device
also has an I2S input port and I2S output port
interface. The I2S input port allows other external
audio sources to use the class-D amplifier to
share the speakers. The I2S output port allows
other high performance or high output power
audio
device
requirement
(i.e.
AD82586/AD83586/AD82587).
