So, In case of inverting op-amp, there are no current flows into the input terminal, also the input Voltage is equal to the feedback voltage across two resistors as they both share one common virtual ground source. Due to the virtual ground, the input resistance of the op-amp is equal to the input resistor of the op-amp which is R2.
This R2 has a relationship with closed loop gain and the gain can be set by the ratio of the external resistors used as feedback. As there are no current flow in the input terminal and the differential input voltage is zero, We can calculate the closed loop gain of op amp. Learn more about Op-amp consturction and its working by following the link. Gain of Inverting Op-amp In the above image, two resistors R2 and R1 are shown, which are the voltage divider feedback resistors used along with inverting op-amp.
R1 is the Feedback resistor Rf and R2 is the input resistor Rin. Op-amp Gain calculator can be used to calculate the gain of an inverting op-amp. Practical Example of Inverting Amplifier In the above image, an op-amp configuration is shown, where two feedback resistors are providing necessary feedback in the op-amp. The resistor R2 which is the input resistor and R1 is the feedback resistor.
The input resistor R2 which has a resistance value 1K ohms and the feedback resistor R1 has a resistance value of 10k ohms. We will calculate the inverting gain of the op-amp. The feedback is provided in the negative terminal and the positive terminal is connected with ground.
Now, if we increase the gain of the op-amp to times, what will be the feedback resistor value if the input resistor will be the same? As the lower value of the resistance lowers the input impedance and create a load to the input signal. In typical cases value from 4. When high gain requires and we should ensure high impedance in the input, we must increase the value of feedback resistors.
But it is also not advisable to use very high-value resistor across Rf. Higher feedback resistor provides unstable gain margin and cannot be an viable choice for limited bandwidth related operations. Typical value k or little more than that is used in the feedback resistor. We also need to check the bandwidth of the op-amp circuit for the reliable operation at high gain. One important application of inverting op-amp is summing amplifier or virtual earth mixer.
An inverting amplifiers input is virtually at earth potential which provides an excellent mixer related application in audio mixing related work. As we can see different signals are added together across the negative terminal using different input resistors. There is no limit to the number of different signal inputs can be added. The gain of each different signal port is determined by the ratio of feedback resistor R2 and the input resistor of the particular channel. Also learn more about applications of the op-amp by following various op-amp based circuits.
