GENERAL DESCRIPTION
The LY8662 is a dual bridge-connected audio power
amplifier. It is capable of driving 4Ω speaker load at
a continuous average output of 2.0W / 10%
distortion (THD+N) from a 5.5V power supply. It
primarily designed for high quality application in
other portable communication device and portable
and desktop computers device.
The audio amplifier features low power consumption
in shutdown mode. And it has an internal thermal
shutdown protection feature.
LY8662 audio amplifier was designed specifically to
provide high quality output power with a minimal
amount of external components. The LY8662 does
not require output capacitors, and it is ideally suited
for other low voltage applications or portable
electronic devices where minimal power
consumption is a primary requirement.
