Forum Post: RE: DAC3484 Power Consumption (Pin Description)
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...

All these formats can be supported, yes.The PSF formats are really interlaced but the data sent is progressive, so it is the responsibility of the data source to send the correct non time shifted field...

Denis,You do not need to use separate LDOs for the 1.2V rails. You could use ferrite bead to isolate the AC ripple noise while passing DC voltage. A good example would be the Murata BLM41PG102SN1L,...

The AIC3262 can do this but it's a much more complex codec in a WCSP. Alternatively you can use a codec (AIC3254) with an external class-D speaker driver like the TPA2012.
