GENERAL DESCRIPTION
The LY8006 is a high efficiency, 3.3 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 LY8006 is designed to meet of portable
electronic devices. The LY8006 is a single 5.5V
power supply, it is capable of driving 4Ω speaker
load at a continuous average output of 3.3 W with
10% THD+N.
In cellular handsets, the earpiece, speaker phone,
and melody ringer can each be driven by the
LY8006.The gain of the LY8006 is externally
configurable which allows independent gain control
from multiple sources by summing the signals.
Output pin short circuit ( short to output pin, short to
ground and short to VDD ) protection prevent the
device from damage during fault conditions.
APPLICATION
„ Portable electronic devices
„ Mobile Phones
„ PDAs
