I have a question about the XTAL1 pin of AD7176-2.
I will use the internal clock of AD7176-2.
And, I do not use the clock output from AD7176-2 to the outside.
In that case, how should I process an unused XTAL1 pin?
The unused XTAL1 pin can be leave floating, however if you wish to have this pin tied off so that the design does not have any floating pins then you connect this pin to DGND.
