Differential Op Amp Gain Calculator. Op amp voltage and gain calculator this calculator determines the output voltage and gain for an op amp given it s resistor values and dc input values. Figure 7 shows a screen shot of the fully differential amplifier component calculator.
The gain of the op amp depends of the selected configuration. Cmrr db 6 80 74 db. Below is a list of op amp calculators which calculate the gain of the circuit based on the values that you enter.
Based on the resistor tolerances this calculator will show the output common mode voltage vocm and the total voltage vout at the differential amplifier output.
Provide the values of the resistors the input voltages and the supply voltages and press the calculate button. Vocm will alter the ideal output voltage which can be calculated when the resistors are perfectly matched. Compatibility issues user must have software capable of reading microsoft excel spreadsheets. This calculator helps calculate the values of the output voltage and the inverting and non inverting gains of an operational amplifier.
