We plan to use the AD8302 to measure the phase (few degrees, <5) of signals with different amplitudes in the 250kHz-25MHz range. We need phase measurements with considerable precision; ~0.1 deg. Can we restrict the phase range of the AD8302 to be narrow (say 5-10 deg), but with high precision? The default slope is 10mV/deg; a 100-fold increase would be most desirable in order to discriminate the phase differences.
We are currently using a TSSOP-DIP adapter and a breadboard, in conjunction with a ucontroller, to verify if the AD8302 will meet our requirements. Any suggestions as to how to implement an optimal arrangement will be appreciated.
Thanks Joel, will try next week and will let you know.
Would you pls inform us about your experience of possibility of slope increment and well work of AD8302 by more accuracy?
