DESCRIPTION

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.
