DESCRIPTION
The MS6333 is an integrated 16-bits voltage-output Digital-to-Analog Converter (DAC) and class AB stereo
headphone driver. The MS6333 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 MS6333 ideally suited for use in digital audio equipment.
