The synchronous wave-detection circuit composed of the MCI496L is as shown in the figure. The MCI496L is the differential circuit that is composed of the geminate transistor, the output uses the collector electrode open-circuit mode, you need to add the load resistor with it if you want to use it. The 3-time gain level shift circuit is composed of A1, the RP2 can be used to adjust the offset voltage to ensure the differential balance. When the input signal is larger than 300mV, the internal differential amplifier of MCI496L will be in the saturated state, so at the signal input Vi port and the benchmark phase input UREF port, the attenuation network is composed of the R1, R2 and R3. So the input signal of the MCI496L can be a few volts.
