LY8893

® LY8893 Rev. 1.4 1.4 Watt Audio power Amplifier with Active-high shutdown mode GENERAL DESCRIPTION The LY8893 is a 1.4 Watt audio power amplifier. And the LY8893 primarily designed for high quality application in other portable communication device. It is capable of driving 8 Ω speaker load at a continuous average output of 1.4W / 10% distortion (THD+N) from a 5.0V power supply. A feature of the LY8893 amplifier to switch BTL mode and headphone mode (single-ended) is accomplished using the headphone sense pin. And the LY8893 audio amplifier features low power consumption shutdown mode. It is achieved by driving the shutdown pin with logic high. Besides the LY8893 has an internal thermal shutdown protection feature. The LY8893 amplifier was designed specifically to provide high quality output power with a minimal amount of external components. The LY8893 does not require output capacitors, and the LY8893 is ideally suited for other low voltage applications or portable electronic devices where minimal power consumption is a primary requirement.
