In my design I need to convert differential sinus wave into square wave (for frequency measurement by FPGA). The two sinus inputs are 180 phase inversion from one to another, 100-10kHz frequency. Due to high input voltage (amplitude of 50V max), a resistor divider stage is necessary. A low pass filter will halp to…
I thought to use a differential amplifier stage follow by comparator stage.
Any suggestion about a certain components that can do that kind of job? I don’t care about the price of the component, or the voltage supply…
If you’ll have an evaluation board I will be happy to purchase. Further more, if you’ll have a Multsim component/ simulation please let me know
