AD5144 Operation

Hello,

 

I received a couple of questions about AD5144 operation from our customer.  

 

1) We can see following description in the datasheet of AD5144.

    "When a desirable wiper position is found, this value can be stored in the EEPROM memory. Thereafter, the wiper   

    position is always restored to that position for subsequent power-ups."

   Does this means the RDAC value will be automatically loaded from EEPROM?

 

2) The customer connect VDD and VLOGIC to same power supply (+3.3V). And also they connect LRDAC, RESET and WP to VLOGIC. Are there any problem in this setting?

 

Best regards,

Akira
