DESCRIPTION The MS6821 is a 16-bits voltage-output Digital-to-Analog Converter (DAC) integrated class AB stereo headphone driver and stereo speaker power amplifier. It can drive 2W of continuous average power into a dual 4Ω bridged-tied (BTL) speaker or 2 * 90mW into stereo 32Ω single ended (SE) headphone. The 16-bit DAC supports general and popular formats as I2S, Right justified. The volume control offers wide range of gain and attenuation for 4-set stereo input. All of the functions are set by I2C interface. The MS6821 has goo...
