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.

16-Bit Stereo Audio DAC & Headphone Driver REV1 8 www.mosanalog.com POWER DOWN AND MUTE FUNCTION A microcontroller or microprocessor control power and mute function timing on MS6333 is shown in Figure 3. It could prevent pop noise effectively when power on and power off. The signals of power down function (pin5) and mute function (pin13) are ignored during initial time 350ms when power on. It is better to control mute function after 1sec. The sequence is mute on and then power down when power off. PD VTM POWER 350ms 1sec Voutput >0sec Power on: Delay >350msec from power on to mute off. Power off: Delay >0sec from mute on to power off. Fig.3 Power and mute function timing.
