What op amp circuit configuration is this? An inverting summing amplifier. A non-inverting summing amplifier. A difference amplifier circuit. Find an expression for the output voltage upsilon_o in terms of the input voltage upsilon_a. Assume that upsilon_o is in volts. Suppose R_j = 20 k ohm. Express your answer in terms of upsilon_a. Suppose upsilon_a = 5 V. What value of R_f will cause the op amp to saturate? Express your answer to three significant figures and include the appropriate units.
