Handbook of Operational Amplifier Applications (Rev. B)

using a comparator instead of an operational amplifier. There are ways of safely using an operational amplifier as a comparator – if the output stage is designed to be used that way - as in a voltage limiting operational amplifier – or if clamping is added externally that prevents the output from saturating. These applications are shown.
