2.5 W Mono Filterless Class D Audio power Amplifier (WCSP / DFN)
GENERAL DESCRIPTION
The LY8010 is a high efficiency, 2.5 W mono 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 LY8010 is designed to meet of mobile phones
and other portable electronic devices. The LY8010
is a single 5V supply, it is capable of driving 4Ω
speaker load at a continuous average output of 2.5
W with 10% THD+N. Not external heat-sink is
required.
In cellular handsets, the earpiece, speaker phone,
and melody ringer can each be driven by the
LY8010.
Output pin short circuit ( short to output pin, short to
ground and short to VDD ) protection prevent the
device from damage during fault conditions.
