GENERAL DESCRIPTION

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

minimal

power

consumption

is

a

primary

requirement.
