LPA4871

Overview
The LPA4871 is a 3W, mono Class AB audio power amplifier. The operating voltage is 2.5-5.5V, which is BTL bridged. Under the condition of 5V power supply, it can provide 4Ω load with THD less than 10% and average output power of 3.0W. In shutdown mode, the current is typically less than 0.5μA.
Designed to provide full power, high fidelity audio output, the LPA4871 requires only a small number of peripheral components. The output does not require an external coupling capacitor or lift capacitor. The SOP-8 package saves circuit area and is ideal for mobile phones and Various mobile devices and the like are used on low voltage, low power applications.
