GENERAL DESCRIPTION
The LY8210 is a high efficiency, 2.5 W stereo class
D audio power amplifier. It is a low noise, filterless
PWM architecture eliminates the output filter,
reducing external component count, system cost,
and simplify design.
The LY8210 is designed to meet of Multimedia
application includes mobile phones and other
portable electronic devices. The LY8210 is a single
5V supply, it is capable of driving 4Ω speaker load at
a continuous average output of 2.5 W/CH with 10%
THD+N.
In cellular handsets, the earpiece, speaker phone,
and melody ringer can each be driven by the
LY8210. Output pin short circuit ( short to output pin,
short to ground and short to VDD ) protection
prevent the device from damage during fault
conditions.
