LM4892M/NOPB

Audio Amplifiers Overview

The LM4892M/NOPB is a single-channel Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 1 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.7%. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and draws a typical quiescent current of 6.5 mA. It features integrated thermal protection and shutdown capabilities, housed in an 8-pin SOIC surface-mount package.
