Schematic Circuit Diagram Op-Amp as a Window voltage detector proteus simulation

To detect the arrival of a particular range of voltage(s) from the swing of an input signal, this circuit is used. Two Op-Amps in comparator mode are used in this circuit. A lower comparator monitors the minimum value of the desired range and upper comparator monitors the maximum value of the desired range. POT Upper and POT Lower are presets for minimum and maximum values.

Op-Amp as Window Voltage Detector

  1. As in the above image, when the input voltage is less than the Minimum value, then output of Lower Comparator and Upper Comparator are low. The voltages at cathodes of the diode AND Gate are High and Low, so the output is low.

  • When the input voltage is higher than the maximum preset value, the output of LC is High and UC is High.The voltages at cathodes of the diode AND Gate are Low and High, so the output is Low.

Window Voltage Detector with Dual Voltage supply
