Audio Amplifiers datasheet and documents for LM4849MH/NOPB

LM4849MH/NOPB

Audio Amplifiers Overview

The LM4849MH/NOPB is a stereo audio power amplifier in an HTSSOP package. It delivers 2W into 4Ω or 2.2W into 3Ω with less than 1.0% THD+N. The device features DC volume control, input multiplexing, and switchable bridged/single-ended modes. Operating voltage ranges from 2.7V to 5.5V. Quiescent current is typically 15mA, while shutdown current drops to 0.7µA. It includes click-and-pop suppression and thermal protection.

Audio Amplifiers Feature Summary

Integrated DC volume control interface for external gain adjustment
Input multiplexer allowing selection between two independent audio sources
Switchable operation between single-ended and bridged configurations
Click and pop suppression circuitry minimizes transient noise during power cycles

Audio Amplifiers Applications

Portable and desktop computers
Multimedia LCD monitors and televisions
Portable radios and PDAs

Audio Amplifiers Procurement Notes

Verify the obsolete status of this component before procurement. Confirm that the HTSSOP package pinout matches the design requirements. Ensure the PCB layout accommodates the exposed die attach paddle for proper thermal dissipation. Check if alternative components are available due to end-of-life status.

Audio Amplifiers Selection Notes

Select this amplifier for applications requiring integrated volume control and input switching. Consider the thermal management requirements when driving low impedance loads like 3Ω or 4Ω. Verify that the supply voltage range fits within the 2.7V to 5.5V specification. Evaluate the need for bridged mode to maximize output power.

Audio Amplifiers Part Context

This part belongs to Texas Instruments' Boomer audio amplifier family. It is designed for high-quality audio performance with minimal external components. The LM4849 integrates multiple functions typically found in separate chips, simplifying system design for portable multimedia devices.
