DESCRIPTION
The MS6332 is an integrated 16-bits voltage-output Digital-to-Analog Converter (DAC) and class AB stereo
headphone driver. The MS6332 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 MS6332 ideally suited for use in digital audio equipment.

POWER DOWN AND MUTE FUNCTION
Power down and mute functions are controlled by the audio input pins (WS, BCK). The initial status is in the mute on
and the power down modes. The 20 clock counts is to switch the power down mode and the 18 clock counts is to switch
the mute mode. In changing these modes, the clock BCK should not exist in WS=1, and always exists in WS=0.

The initial status is in the power down mode.
