Product Summary

The LM4871MX is a bridge-connected audio power amplifier capable of delivering typically 1.1W of continuous average power to an 8Ω load with 0.5% (THD) from a 5V power supply.The LM4871MX features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4871MX can be configured by external gain-setting resistors. The LM4871MX can be applied in portable computers, desktop computers, and low voltage audio systems.
