GENERAL DESCRIPTION
The LY8890 is a 1.0W audio power amplifier. It is
capable of driving 8Ω speaker load at a continuous
average output of 1.0W/1% distortion (THD+N) from
a 5.0V power supply. The LY8890 primarily
designed for high quality application in other
portable communication device. And the LY8890
audio amplifier features low power consumption
shutdown mode. It is achieved by driving the
shutdown pin with logic low. And the LY8890 has an
internal thermal shutdown protection feature.
The LY8890 audio amplifier was designed
specifically to provide high quality output power with
a minimal amount of external components. The
LY8890 does not require output capacitors, and the
LY8890 is ideally suited for other low voltage
applications or portable electronic devices where
minimal power consumption is a primary
requirement.
