Description
AD62557 is a highly integrated USB single
chip for Stereo/Mono speaker. Many useful features
are prog rammable with p ins or I 2C co ntrol. Whe n
using the power supplied from the USB port (USB
3.0), AD6 2557 ca n drive a p air of up to 2.1W into
4ohm speakers du e to the built-i n, hi gh ef ficiency
and hig h p erformance Class-D amplifiers. T he
device also has an I2S input port and I2S output port.
The I 2S input port allo ws oth er ex ternal a udio
sources to use the Cla ss-D amplifie r to share the
speakers. Th e I 2S output port allows other high
performance audio device (i.e. AD82586/AD82581).
