The FilterLab tool simplifies active filter design and gives users full schematic diagrams of the filter circuit with component values and displays the frequency response, all of which make designing variable filters utilizing op amps easier.
For this application, the appropriate choice is an op amp with slew rates at least equal to the rise time of the digital signal and a bandwidth two to three times at least that of the incoming signal.
So, bandwidth and slew rate having been established, designers can find a significant number of viable op amps from major manufacturers that will meet the requirements.
