Question

About the AD4523 For AVDD1 = +15 V , AVDD2 = 5 V , AVSS = &minus;15 V . - what is the current supply value for Ivdd1 ? VLOGIC I=3.3V can be coupled to VLDO or should be coup3led to extern alim? What is the difference ?

Hi, 
 Apologies. Can you clarify the part number please so we can better support you. 
 If this is a DAC related query, I'd recommend to move or post this to Precision DACs - EngineerZone (analog.com) community. Someone there may be able to assist you. 
 Thanks,

Hi, 
 Current for AVDD1 (AIDD1) is typically around 1mA. 
 VLOGIC can be supplied by external voltage or by the VLDO pin. VLDO pin is provided in the device for design convenience. 
 Best regards,
