BUF01900 power up sequence


 I would like to know what are the effects if a wrong power up sequence is used in particular if VS starts before VSD.

In addition to higher power dissipation as described in the datasheet, damage can occur?

The customer is also detecting(after a wrong power up sequence) that the first data transfer from OTP to DAC is uncorrect and this is verified reading the DAC register: do you think this is possible?

Repeating the transfer, the loading to DAC becomes correct.
