The LY8601 is a dual 0.1W audio power amplifier. It
is capable of driving 16Ω load at a continuous
average output of 0.1W/0.1% distortion (THD+N)
from a 5.0V power supply.
The LY8601 primarily designed for high quality
application in other portable communication device.
And the LY8601 audio amplifier features low power
consumption shutdown mode. It is achieved by
driving the shutdown pin with logic high and it has
an internal thermal shutdown protection feature.
The unity-gain stable LY8601 can be configured by
external gain-setting resistors.
The LY8601 audio amplifier was designed
specifically to provide high quality output power with
a minimal amount of external components. The
LY8601 does not require bootstrap capacitors, and
the LY8601 is ideally suited for other low voltage
applications or portable electronic devices where
