Other Parts Discussed in Thread: TAS5707
Hi
Briefly, we think there is the following power sequence for TAS5707.
Power Up: AVDD/DVDD = 3.3V applied first, then PVDD=20V applied
Power Down:PVDD powered down, then AVDD/DVDD powered down
Could you please tell us what trouble would be expected if the device is not compliant to the above sequences?
I mean the following cases:
Power Up: PVDD first, then AVDD/DVDD -> It would be NG? What's happen?
Power Down:AVDD/DVDD down, then PVDD down -> It would be NG? What's happen?
I hope to hear from you.
BestRegards
