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 4£[ bridged-tied (BTL) speaker or 2 * 90mW into stereo 32£[ 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 good feature for portable equipment, including wide voltage operation 2.4V~5.5V, low power consumption, flexible power management, component less and small package TSSOP28, make the MS6821 ideally suitable for use in the portable digital audio equipments. |
