What is meant by window comparator?
Glossary Term: Window Comparators Definition. A device, usually consisting of a pair of voltage comparators, in which output indicates whether the measured signal is within the voltage range bounded by two different thresholds (an “upper” threshold and a “lower” threshold).
What is the use of lm393?
The LM393 IC is a low-power, single-supply, low-offset voltage, double, differential comparators. Generally, a common comparator IC is a tiny voltmeter by included switches. It is used to calculate the voltages at two dissimilar terminals and contrasts the dissimilarity in voltage quantity.
What is the name of the window comparator?
One which triggers an op-amp comparator on detection of some upper voltage threshold, VREF (HIGH) and one which triggers an op-amp comparator on detection of a lower voltage threshold level, VREF (LOW). The voltage levels between these two upper and lower reference voltages is called the “window”. Consider the circuit presented in Figure 1.
How does a window comparator work in a voltage circuit?
A window comparator is a circuit that operates within a certain frame, or window, of voltage. Normally how a voltage comparator works when by itself is that when the voltage rises above a certain level at the inverting terminal, the output turns on. Any voltage above this reference level keeps the output on.
How to make a window comparator for temperature control?
Window Comparator 1 Background. Consider the circuit presented in Figure 1. 2 Hardware Setup. Build the following breadboard circuit for the window comparator circuit. 3 Procedure. Use the first waveform generator (W1) as source to provide a Triangular signal with 5V amplitude peak-to-peak, 100Hz frequency and 2.5V offset.
Why do you need two comparators in a circuit?
This is a window comparator, because the output only turns on when the input voltage is within this window of voltage. In order to create a window comparator circuit, 2 comparators are needed. We will use 2 LM741 chips to build our window comparator circuit.
