Technical FAQs 4

What is the difference between a voltage comparator and a non inverting comparator?

Fig1 shows a voltage comparator in inverting mode and Fig shows a voltage comparator in non inverting mode. Non inverting comparator. In non inverting comparator the reference voltage is applied to the inverting input and the voltage to be compared is applied to the non inverting input.

How does a non inverting comparator work?

Non inverting comparator. In non inverting comparator the reference voltage is applied to the inverting input and the voltage to be compared is applied to the non inverting input. Whenever the voltage to be compared (Vin) goes above the reference voltage , the output of the opamp swings to positive saturation (V+) and vice versa.

What is a positive voltage comparator?

The basic configuration for the positive voltage comparator, also known as a non-inverting comparator circuit detects when the input signal, V IN is ABOVE or more positive than the reference voltage, V REF producing an output at V OUT which is HIGH as shown.

What is a negative voltage comparator?

The basic configuration for the negative voltage comparator, also known as an inverting comparator circuit detects when the input signal, V IN is BELOW or more negative than the reference voltage, V REF producing an output at V OUT which is HIGH as shown.
