Other Parts Discussed in Thread: DAC3164, DAC3151, DAC3171, DAC3154, , DAC3161
Hi,
In DA3174 datasheet (SLAS837B –APRIL 2013–REVISED JANUARY 2017)
Pins 63,62,52,51 are marked as NC in "Pin Functions" Table it is mentioned that
these pins can be floated or connected to ground., but in page 45, Fig 59. "Layout Example"
it appears to me that they are all connected to VDDA18 !.
It is also mentioned that DAC3174 is compatible to DAC3154,DAC3164 DAC3151, DAC3161 and DAC3171
so I checked out "DAC31X1 EVM" schematics, there also-these NC pins- are connected to VDDA18.
Which method is correct should I left them floated, connect them to the GND or VDDA18 ?
Thank you in advance
Best Regards
Amirali
