® Rev. 1.4 1.0 Watt Audio power Amplifier LY8891 FEATURES 2.5V~5.5V Power supply. Thermal shutdown Protection. Low current shutdown mode No capacitors and networks or bootstrap capacitors required „ Low noise during turn-on and turn-off transitions „ Lead free and green package available. (RoHS Compliant) „ Space Saving Package -- 8-pin MSOP package. -- 8-pin DFN Package „ „ „ „ GENERAL DESCRIPTION The LY8891 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 LY8891 primarily designed for high quality application in other portable communication device. And the LY8891 audio amplifier features low power consumption shutdown mode. It is achieved by driving the shutdown pin with logic low. And the LY8891 has an internal thermal shutdown protection feature. The LY8891 audio amplifier was designed specifically to provide high quality output power with a minimal amount of external components. The LY8891 does not require output capacitors, and the LY8891 is ideally suited for other low voltage applications or portable electronic devices where minimal power consumption is a primary requirement.
