DAC5674 Sleep Pin Physical Connection

Hello,

In the datasheet for the DAC5674, it states that SLEEP mode is activated by applying logic level 1 to the SLEEP pin (e.g. connecting SLEEP to AVdd).  In the electrical characteristics of the data sheet it has the following

 

However, on the eval board: DAC5674EVM, the schematics show the SLEEP pin connected to IOVdd which has a stated range of 1.65V to 3.6V in the datasheet.  Am I correct to assume that the SLEEP function will not work on the eval board if the IOVdd is 1.8V and not 3.3V.  Is this a mistake on the eval board?

 

Thanks,
Eric

  • Hi Eric,

    There is typo in the datasheet. The parameter should be 0.7 *IOVDD instead of AVDD.

    So to answer your question the SLEEP function will work with either 1.8V or 3.3V IOVDD.
