The AD53042 is an ultrahigh speed window comparator with latch. It uses a high speed monolithic process to provide high dc accuracy without sacrificing input voltage range. On-chip connection of the common input eliminates the contributions of a second bonding pad and package pin to the input capacitance, resulting in a maximum input capacitance of 2 pF. The AD53042 employs a high precision differential input stage with on-chip parasitic capacitance compensation, providing an input voltage range of -2 V to +7 V.
