I am using AD664 , 4-channel DAC.
duriing first time power on 4 -channels are was unipolar (default sets) .
Testing purpose i changed all bipolar to unipolar by writting mode register 0xFFX.
Now i need to change return back to all unipolar .
its not happening , i am applying reset pulse . but did not restore default condition.
reset pulse is it required min 80 ns to 100 ns ?
can some one suggest me how way can i get unipolar setting again.
