AD5542A Power-on-Reset does not work

Hi Support team

I 'm evaluating the AD5542A, i rarely found the non-MID scale output when the power is turned on.

To ensure POR operation, are there any recommended conditions such as power supply slew rate or linear increase?

VDD and VLOGIC rising waveforms are attached for reference. Can you tell me if there is any problem?

Best regards,

Blue is VDD (5V) and light blue is VLOGIC (3.3V).
