PARAMETER MEASUREMENT INFORMATION
Response time is defined as the interval between the application of an input step function and the instant when the
output reaches 50% of its maximum value. Response time, low-to-high-level output, is measured from the trailing
edge of the input pulse. Response-time measurement at low input signal levels can be greatly affected by the input
offset voltage. The offset voltage should be balanced by the adjustment at the inverting input (as shown in Figure 3)
so that the circuit is just at the transition point. Then a low signal, for example, 105-mV or 5-mV overdrive, causes
the output to change.
