LM4884 Datasheet Btl Output Stereo Audio Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4884 Boomer 2.1W Differential Input, BTL Output Stereo Audio Amplifier with RF Suppression and Shutdown April 2005 LM4884 2.

General Description

The LM4884

Key Features

  • differential stereo inputs, BTL (bridgetied load) outputs, and four externally selectable fixed gains. The LM4884 also features proprietary internal circuitry that suppresses the coupling of RF signals into the chip. This is important because certain types of RF signals (such as GSM) can couple into audio amplifiers in such a way that part of the signal is heard through the speaker. The RF suppression circuitry in the LM4884 makes it well-suited for notebook and portable.
