The inverting amplifier in the figure is ideal with a gain of 4.
1- Determine Rin.
2- Determine the range of input voltages that will keep the op amp in its linear operating region.
3- Suppose you wish to amplify a 6 V signal, using your design from part A with a variable feedback resistor. What is the largest value of feedback resistance that keeps the op amp in its linear operation region?
4- Using the resistor value from part C, what is the new gain of the inverting amplifier?
