DESCRIPTION
The MS6330 is an integrated 16-bits voltage-output Digital-to-Analog Converter (DAC) and class AB stereo
headphone driver. The MS6330 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, precluded zero-crossing
distortion and ensures high quality audio reproduction.
These unique features, combined with its exceptional performance, make the MS6330 ideally suited for use in digital
audio equipment.

POP NOISE REDUCTION AS POWER-ON-OFF
It is effective to prevent the power-on-off pop noise by controlling /PD and PDPR pins. The better control timing is as
below. Please refer to the circuit diagram in the page 8.
VDD
PD
>100ms
>100ms
PDPR
>350ms
Music
Power-on sequence
Power-off sequence
In power-on sequence, the initial state of /PD is low and PDPR is high, and then PDPR sets low after the /PD sets high
at least 100ms. In power-off sequence, enable PDPR function and delay 100ms, and then sets low to /PD.
POWER DOWN SEQUENCE
The power down sequence is a power-save mode (VDD is on), the power down current of MS6330 is less than 1uA. The
control timing is as below.
PD
>100ms
Delay time
PDPR
>350ms
Music
Disable Power-down
Enable Power-down
The delay time is decided by the value of the bypass capacitor. It is 5second for 10uF bypass capacitance.

Function description
Label 1: Supply Input
The AVDD and DVDD should be the same supply voltage, the supply range is 2.5~5.5 VDC.
Label 2: Reset MCU Switch
As pressed the button once , the system will be loaded default value. The MS6330 is power-down mode.
Label 3: Power-down Switch (shutdown MS6330)
As pressed the button once, the chip status will be switched to power-down mode or active mode (disable powerdown mode). The default status is power down mode initially.
Label 4: Power-down LED (shutdown MS6330)
The MS6330 is power-down mode as the LED is brightness. On the other hand, darkness is active-mode.
Label 5: Digital Audio Input
Connected to digital audio signals and used right-justified format.
Label 6: Headphone Jack
Used 3.5mm diameter of headphone with 32ohm.
