Denis,

[quote user="Denis Litvinov"]Are all currents -  IAVDD , IPLLAVDD, IOVDD, need 123 mA (Typ) or each of them? (123mA * 3 = 369 mA? ) [/quote]

You are correct. The 123mA includes all the currents for AVDD, PLLAVDD, and IOVDD rails. We have noted this in note (4).

[quote user="Denis Litvinov"]And all currents of one type need the value which is written in the datasheet? For example MODE1:  ALL IDACVDD pins need 35 mA, not that each needs 35 mA. [/quote]

Correct. We listed the the current required for each individual rail, not the individual pins. The overall DACVDD rails requires 35mA, not 35mA each pin.
