.. LM4681 10 Watt Stereo CLASS D Audio Power Amplifier with Stereo Headphone Amplifier and I2C/SPI Volume Control March 2006 LM4681 10 Watt Stereo CLASS D Audio Power Amplifier with Stereo Headphone Amplifier and I2C/SPI Volume Control General Description The LM4681 is a fully integrated single supply, CLASS D audio power amplifier solution. The LM4681 utilizes a proprietary balanced pulse-width modulation technique that lowers output noise and THD and improves PSRR when pared to conventional pulse width modulators. The LM4681 also Features a stereo headphone amplifier that delivers 80mW into a 32Ω headset with less than 0.5% THD. The LM4681’s I2C/SPI (selectable)...
