Hi all,

 

We are using ADV7393 in one of our designs .We are operating ADV7393 at low drive mode with ADA4431 as a output filter.

 

Currently we are looking into power management of ADV7393. I have couple of questions regarding this .

 

  • According to the datasheet DAC auto-power down mode is supported only in full drive mode.Is there any methods to put ADV7393 DAC into auto power down mode in low drive mode ?
  • If we put DAC into auto power down mode ( in high drive mode ) will the currents of all power supplies be reduced or is it just Vaa current ? Is there any method apart from sleep mode to reduce the current of all power supplies ?

 

Regards ,
