The LY8898 is a 3.2W audio power amplifier. It is capable of driving 3? speaker load at a continuous average output of 3.2W with less than 10% distortion (THD+N) from a 5.0V power supply and 4? speaker load at a continuous average output of 2.7W with less than 10% distortion (THD+N) from a 5.0V power supply. The LY8898 primarily designed for high quality application in other portable communication device. And the LY8898 audio amplifier features low power consumption shutdown mode. It is achieved by driving the shutdown pin with logic high. And the LY8898 has an internal thermal shutdown protection feature. The LY8898 audio amplifier was designed specifically to provide high quality output power with a minimal amount of external components. The LY8898 does not require output capacitors, and the LY8898 is ideally suited for other low voltage applications or portable electronic devices where minimal power consumption is a primary requirement.
