I am working on a design that involves an AD5722, operating from dual supplies (± 15 V) and bipolar output (output range ± 10 V).
I have two "simple/dummy" questions:
1 - Exposed Paddle: in data sheet (Rev. F | Page 10 of 32) says: "...This exposed paddle must be connected to the potential of the AVSS pin...". When working with symmetric supply and bipolar output: Couldn't it be connected to GND / DAC_GND or SIG_GND?
2 - NC Pins (2, 4, 6, 12, 13, 22): Can they be tie to GND / DAC_GND or SIG_GND?
Thanks for the support you provide.
