Does anyone know a satable circuit to use with and ATmega 3.3V as a pulse peak limiter with a good band width .
Basically the circuit needs to accept a frequency as input, or odometer signal, reed sensor who close to ground all the time pass to the magnet etc.
Maybe a comparator with a peak limiter/clamping circuit

thanks
 

If you are using a comparator, why do you need a "peak limiter/clamp"? What is your input voltage? If you are just worried about overvoltage on the input, couldn't you use a voltage divider?
