GENERAL DESCRIPTION
The LY8897 is a 2.7W audio power amplifier. It is
capable of driving 4Ω speaker load at a continuous
average output of 2.7W with less than 10%
distortion (THD+N) from a 5.0V power supply and
8Ω speaker load at a continuous average output of
1.7W with less than 10% distortion (THD+N) from a
5.0V power supply.
The LY8897 primarily designed for high quality
application in other portable communication device.
And the LY8897 audio amplifier features low power
consumption shutdown mode. It is achieved by
driving the shutdown pin with logic low.
And the LY8897 has an internal thermal shutdown
protection feature.
The LY8897 audio amplifier was designed
specifically to provide high quality output power with
a minimal amount of external components. The
LY8897 does not require output capacitors, and the
LY8897 is ideally suited for other low voltage
applications or portable electronic devices where
minimal power consumption is a primary
requirement.
