POP NOISE REDUCTION AS POWER-ON-OFF

16-Bit Stereo Audio DAC & HP Driver with PD

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.

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 (V_DDis on), the power down current of MS6330 is less than 1uA. The

control timing is as below.

>100ms

>350ms

Delay time

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.
