Description
AD62557 is a highly integrated USB single
chip for Stereo/Mono speaker. Many useful features
are programmable with pins or I2C control. When
using the power supplied from the USB port (USB
3.0), AD62557 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.
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 audio device (i.e. AD82586/AD82581).
