Hi,
A customer has two questions about PCM1803A power supply.
Q1. Does PCM1803A have any power supply sequence requirement?
He thinks two power pins must be powered up simultaneously, if PCM1803A has internal protection diodes between VCC and VDD.
Q2. Does PCM1803A have a requirement power up time from zero volt to minimum operating voltage?
Currently, their power supplies need up to several ten msec or so as rise time.
Best regards,
Akio Ito
