GENERAL DESCRIPTION
The LY8005 is a high efficiency, 2.3 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 LY8005 is designed to meet of mobile phones
and other portable electronic devices. The LY8005
is a single 5V supply, it is capable of driving 4Ω
speaker load at a continuous average output of 2.3
W with 10% THD+N. The LY8005 has high
efficiency with speaker loads compared to a typical
Class AB amplifier.
In cellular handsets, the earpiece, speaker phone,
and melody ringer can each be driven by the
LY8005.The gain of the LY8005 is externally
configurable which allows independent gain control
from multiple sources by summing the signals.
Output short circuit and thermal overload protection
prevent the device from damage during fault
conditions.
APPLICATION
„ Portable electronic devices
„ Mobile Phones
„ PDAs
