The LPA4871 is a 3W, mono Class AB audio power amplifier. Working voltage 2.5-5.5V, using BTL bridge connection, when powered by 5V power supply. Under this condition, it can provide a THD of less than 10% and an average of 3.0W to a 4Ω load. Output Power. In shutdown mode, the current is typically less than 0.5μA.
The LPA4871 is specifically designed to provide full power, high fidelity audio output Designed, it only requires a small number of peripheral components, and the output does not require external coupling capacitors. Or lift-up capacitor, using SOP-8 package, saving circuit area, very suitable for Mobile phones and various mobile devices use low voltage and low power consumption application solutions used on.
