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.

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. Power down timing The initial status is in the power down mode. WS BCK Total 20 clocks Power down mode Power active mode Mute timing The initial status is in the mute on mode.
