The MS6331 is an integrated 16-bit voltage-output Digital-to-Analog Converter (DAC) and class AB stereo headphone driver. The MS6331 is with the excellent Power Supply Rejection Ratio(PSRR). It is fabricated in a CMOS process and features extremely low power dissipation, small package size and easy application. The accuracy of the matched coarse current sources, combined with the unique symmetrical decoding method, preclude zero-crossing distortion and ensures high quality audio reproduction. These unique features, combined with its exceptional performance, make the MS6331 ideally suited for use in digital audio equipment.
