Web4 de mar. de 2024 · Figure 5 signifies the output of a comparator with hysteresis with a fluctuating input voltage. The input signal level is supposed to move over the higher threshold limit (VH = 2.7V) for the opamp output to slip down to logic low (0V). Also, the input signal level needs to move under the Lower threshold for the opamp output to … Web28 de fev. de 2024 · It is measured as voltage relative to time, and the typical unit used in datasheets is volts per microsecond (V/µs). Let’s say you have an op-amp and apply an input signal that would, in an ideal environment, generate an output signal with a slope of 10 V/µs. If the slew rate of the op-amp is 2 V/µs, the output signal will reflect the ...
