In this circuit configuration, the output voltage signal is given to the inverting terminal - of the operational amplifier like feedback through a resistor where another resistor is given to the ground. Here, a voltage divider with two types of resistors will provide a small fraction of the output toward the inverting pin of the operational amplifier circuit.

Non-Inverting Op-Amp Circuit These two resistors will provide necessary feedback to the operational amplifier. Here, the R1 resistor is called a feedback resistor Rf. Because of this, the Vout depends on the feedback network. The Current rule states that there is no flow of current toward the inputs of an op-amp whereas the voltage rule states that the op-amp voltage tries to ensure that the voltage disparity between the two op-amp inputs is zero.

From the above non-inverting op-amp circuit, once the voltage rule is applied to that circuit, the voltage at the inverting input will be the same as the non-inverting input. So the applied voltage will be Vin. Therefore the non-inverting op-amp will generate an amplified signal that is in phase through the input.

Input Impedance In a non-inverting operational amplifier circuit, the input impedance Zin can be calculated by using the following formula. Op-Amps are popular for its versatility as they can be configured in many ways and can be used in different aspects. An op-amp circuit consists of few variables like bandwidth, input, and output impedance, gain margin etc. Different class of op-amps has different specifications depending on those variables.

You can learn more about Op-amps by following our Op-amp circuits section. An op-amp has two differential input pins and an output pin along with power pins. Those two differential input pins are inverting pin or Negative and Non-inverting pin or Positive. An op-amp amplifies the difference in voltage between this two input pins and provides the amplified output across its Vout or output pin. Depending on the input type, op-amp can be classified as Inverting or Non-inverting. In this tutorial, we will learn how to use op-amp in noninverting configuration.

In the non-inverting configuration, the input signal is applied across the non-inverting input terminal Positive terminal of the op-amp. As we discussed before, Op-amp needs feedback to amplify the input signal. This is generally achieved by applying a small part of the output voltage back to the inverting pin In case of non-inverting configuration or in the non-inverting pin In case of inverting pin , using a voltage divider network. Non-inverting Operational Amplifier Configuration In the upper image, an op-amp with Non-inverting configuration is shown.

The signal which is needed to be amplified using the op-amp is feed into the positive or Non-inverting pin of the op-amp circuit, whereas a Voltage divider using two resistors R1 and R2 provide the small part of the output to the inverting pin of the op-amp circuit.

These two resistors are providing required feedback to the op-amp. In an ideal condition, the input pin of the op-amp will provide high input impedance and the output pin will be in low output impedance. The amplification is dependent on those two feedback resistors R1 and R2 connected as the voltage divider configuration. Due to this, and as the Vout is dependent on the feedback network, we can calculate the closed loop voltage gain as below.

Also, the gain will be positive and it cannot be in negative form. The gain is directly dependent on the ratio of Rf and R1. Now, Interesting thing is, if we put the value of feedback resistor or Rf as 0, the gain will be 1 or unity. And if the R1 becomes 0, then the gain will be infinity. But it is only possible theoretically. In reality, it is widely dependent on the op-amp behavior and open-loop gain. Op-amp can also be used two add voltage input voltage as summing amplifier.

Practical Example of Non-inverting Amplifier We will design a non-inverting op-amp circuit which will produce 3x voltage gain at the output comparing the input voltage.
