LM4884
2.1W Differential Input, BTL Output Stereo Audio
Amplifier with RF Suppression and Shutdown
General Description
The LM4884 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.
