Question

What is the transfer function of an op amp?

1) Vout/Vin = -Rf/R1
2) Vout/Vin = -Rf/R1 + 1
3) Vout/Vin = -Rf/R1 - 1
4) Vout/Vin = Rf/R1

Answer 1

The transfer function of an op amp is Vout/Vin = -Rf/R1.

Step-by-step explanation:

An op amp, or operational amplifier, is an electronic device that amplifies the difference between two input voltages. The transfer function of an op amp is a mathematical expression that relates the output voltage (Vout) to the input voltage (Vin). The correct transfer function for an inverting op amp amplifier is Vout/Vin = -Rf/R1, which is option 1.
