Suppose that we design an inverting amplifier using 5-percent-tolerance resistors and an ideal op amp. The nominal amplifier gain is -2.What are the minimum and maximum gains possible, assuming that the resistances are within the stated tolerance? What is the percentage tolerance of the gain?
The input, Vin, is differential not single-ended. Design an analog circuit with a transfer function of Vout = 50 Vin + 2.5 powered by a single +5 V supply. You may use any of the analog chips.
