Op-amp stands for “operational amplifier.” An op-amp is so called because it is used for various computational operations such as comparison, addition, subtraction, differentiation, and integral.
However, it is to be noted that anOp-Ampcan be suitably configured to result in a much practicaldifferential amplifier, as shown in Figure 2 If closely observed, one can note that this circuit is just a combination of inverting and non-inverting amplifiers. Hence its output voltage will be ...
Figure 2.The FlexiForce Characterization Kit allows for interchangeable analog circuit modules, such as the Voltage Divider shown here. Inverting and non-inverting op-amp circuit modules are also included with the kit. Image Credit: Tekscan, Inc. Phase 2: Proof-of-Concept After characterizing senso...
The other is the non-inverting input and this is marked with a "+" sign.The op amp is basically a differential amplifier because the output is proportional to the difference in voltage between the two inputs.Operational amplifier equivalent circuit ...

The low pass Butterworth filter is anactive Low pass filteras it consists of theop-amp. This op-amp operates on non-inverting mode. Hence, the gain of the filter will decide by theresistorR1and RF. And the cutoff frequency decides by R and C. ...
terminal, the non-inverting input terminal (+) and the inverting input terminal (-) are considered to have the same voltage applied, that is to say, it can be considered as a virtual short circuit. Therefore, when the positive input terminal (+) is 0V, the voltage at point A is also...
Whereas if a circuit is such that DC current can flow to ground, such as through a resistor, then it is considered to be DC-grounded. A classic example would be a non-inverting op amp configured with the divider feedback resistor connected through a capacitor to ground (AC-grounded), or...
the input voltages marked as A, B and C. The negative feedback was applied through a variable resistor marked as 16 in the circuit. This op-amp circuit had only one input terminal which is inverting input. We will discuss about inverting input and non-inverting input later in this article...
Figure 5 depicts a non-inverting amplifier circuit. If RF= in Fig. 5 and R1=0, the comparator circuit is the same as in Fig. 3. (b). In Figure 5, Vin corresponds to VA in Figure 3. (b). Figure. 5 Ⅲ. Difference between comparator and op amp Comparator circuits can be made wi...
