I have made a couple of trial boards and tried to operate AD5724 on the board.
I set the DB0 to DB3 of the power control register to "1" but could not get any analog output. However only adding to set DB4 to "1",
I could get expected output value.
- According to the data sheet, DB4 is fixed "0" value. Why I could get the expected output by changing DB4 to "1"?
- Is data sheet not correct regarding the DB4 spec, or I should take another way (not change DB4) to solve this issue?
