Hello -
I have a waveform that goes from -10v to 10v. When it reaches 10v, I would like the Schmitt Trigger to output -10v. When the waveform reaches -10v, I would like the Schmitt Trigger to output 10v.
I believe the attached schematic is the standard circuit for doing this. But I am having trouble understanding how. It seems that Schmitt Triggers seem to be "tripped" at the ground voltage, instead of near either rail.
Is there a better op-amp or comparator circuit for this job?
