I need to find the phase difference between two sinusoidal signals (0-1000Hz). Is the ad8302 the only chip available for this? It appears that the 2.7 GHz bandwidth may not be too appropriate since my signals are very low in frequency.
I would assume that there might be a variety of mixer available for this which provides a dc voltage proportional to the phase difference. Would there be other approaches to acquire the phase difference between two analog signals.
