Inverting Amplifier Circuit app for iPhone and iPad

An operational amplifier in an electronic circuit has a non-inverting input terminal and an inverting input terminal. The polarity of the input terminal and the output terminal are the same polarity is a non-inverting amplifier, and the polarity of the input terminal and the output terminal are opposite polarity is called an inverting amplifier. amplifier.
The inverting amplifier circuit has the function of amplifying the input signal and inverting the output.
Inverting Op Amp Resistor Calculator: Calculate gain from the relationship of input to output in an amplifier circuit.
Gain is the ratio of Vout to Vin, ie Vout/Vin= (-I1xR2) / (I1xR1) =- R2/R1.
PS: The gain voltage value is a negative number, indicating that the waveform is inverted.
