PHASE_DETECTOR_WITH_10_BIT_ACCURACY

Signals of identical frequency are applied to sync input (Pin 6) and to the demodulator input (Pin 4), respectively, the demodulator functions as a phase detector with output dc component being proportional to phase difference between the two inputs. The signals must be referenced to 0 V for dual supply operation or to VR/2 for single supply operation.At ± 5-V supplies, the demodulator can easily handle 7-V peak-to-peak signals. The low-pass network configured with the uncommitted amplifier dc output at Pin 1 of the device. The dc output is maximum (+ full-scale) when V1 and V2 are 180°out of phase and minimum (- full-scale) when the signals are in phase.
