General Description

The LM4992 is a stereo audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

It is capable of delivering 1 watt, per channel, of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components.

Overview

LM4992 420mW Stereo Cell Phone Audio Amplifier February 2004 LM4992 420mW Stereo Cell Phone Audio.

Key Features

  • independent shutdown control for each channel and a low-power consumption shutdown mode, which is achieved by driving both shutdown pins with logic low. Additionally, the LM4992 features an internal thermal shutdown protection mechanism. The LM4992 contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions. The LM4992 is unity-gain stable and can be configured by external gain-setting resistors. Key Specifications j Improve.
