We intend to use AD8302 for phase measurements. As per the datasheet there is non linearity near 0 degree and 180 degree. For our application, phase diffrence of 0 to 30 degree is vimportant. should we provide an intentional 90 degree phase shift in one input of AD8302 such that the phase difference VPHS comes in the linear region.
or Is there some other technique to solve this issue ?
