The following signal is presented to me, and will vary in freq, but not amplitude from 10Hz up to around 25 KHz.
Any ideas for a simple circuit that will convert this into a clean 3V3 square wave for feeding into an MCU? Ideally, avoiding phase shift as freq increases (though not as important.)
I am thinking of some sort of schmitt trigger with a large hyst and 1v/3v cross over points, but open to suggestions!
It should also have some noise immunity being an automotive environment.
