Figure 51 shows the OPx13 family response to a 10 mV
overdrive signal when operating in open loop. The top trace
shows the output rising edge has a 15 μs propagation delay,
whereas the bottom trace shows a 7 μs delay on the output
falling edge. This ac response is quite acceptable in many
applications.

The low noise and 250 μV (maximum) offset voltage enhance
the overall dc accuracy of this type of comparator. Note that zero-
crossing detectors and similar ground referred comparisons can be
implemented even if the input swings to −0.3 V below ground.
