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.

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.
