Product details

Description

The LM4871 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.

Features

an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4871 can be configured by external gain-setting resistors. Key Specifications n THD at 1 kHz at 1W continuous average output power into 8Ω n Output power at 10% THD+N at 1 kHz into 8Ω n Shutdown Current 0.5% (max) 1.5W (typ) 0.6 µA (typ) Features n No output coupling capacitors, bootstrap capacitors, or snubber circuits are necessary n Small Outli.
