Description: BTL Output Stereo Audio Amplifier

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

Applications

* in which strong RF signals generated by an antenna from a PC wireless card or a cellular phone may couple audibly into the amplifier. Operating on a single 5V supply, the LM4884 delivers 1.2W, 1.9W, or 2.1W (typ) of output power to an 8Ω, 4Ω, or
