LM4874 - BTL Output Stereo Audio Amplifier
LM4874 Features
* differential stereo inputs, BTL (bridgetied load) outputs, and four externally selectable fixed gains. Operating on a single 5V supply, the LM4874 delivers 1.2W, 1.9W, or 2.1W (typ) of output power to an 8Ω, 4Ω, or 3Ω BTL load (Note 1), respectively, with less than 1% THD+N. The LM4874’s gain is sel
