Ⅰ. What is a voltage comparator? Ⅱ. How does comparator work? Ⅲ. Difference between comparator and op amp Ⅳ. Comparator typical application circuit A voltage comparator (also known as a comparator) is a very common integrated circuit. It can be utilized in V/F conversion circuits, A/D...
Comparator is used to sense the signal of a predefined rich level. If I set a level to sense then I can use a comparator to sense it when the input signal of this level cross more or below the level, suddenly the output is changed from Low to high and high to low. The comparators ...
In the circuit shown in the figure, A1 is an integrator circuit, and A2 is a non-inverting input hysteresis comparator, which acts as a switch. When its output voltage u01=+UZ, the diode D is cut off, the input voltage (Ui>0) is charged to the capacitor C through the resistor R1,...

Comparators feature the same pin configuration as opamps: + Input, - Input, Positive Supply, Negative Supply, and Output pins. However, with comparators either one of the input pins is used as a reference pin (with a fixed voltage), and the difference in voltage between this reference value...
in the datasheet, there have a overdrive voltage minimum requirement, I want to know what's the overdrive voltage. the datasheet show that: Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the comparator ...

There is another approach where an EN pin can be used as a UVLO pin with hysteresis. This would involve another circuit using acomparator. By using some reference voltage source, a comparator could be used to set a threshold on the EN pin such that EN is only HIGH when the input voltage...
What is a phase-locked loop (PLL)? A phase-locked loop (PLL) is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal. PLLs are used to generate, stabilize,modulate, demodulate, filter or recover a signal from ...
