LM4838 Datasheet Stereo 2w Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: LM4838 .ti. SNAS131F – JANUARY 2001 – REVISED MARCH 2013 LM4838 Stereo 2W Audio Power Amplifiers with DC Volume Control and Selectable Gain Check for Samples:.

General Description

The LM4838 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4Ω with less than 1.0% THD or 2.2W into 3Ω with less than 1.0% THD (see Notes below).

Boomer™ audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amount of external ponents.

The LM4838 incorporates a DC volume control, stereo bridged audio power amplifiers and a selectable gain or bass boost, making it optimally suited for multimedia monitors, portable radios, desktop, and portable puter applications.
