An Operational Amplifier Problem
Problem OpAmp3P04

Name__________________________________

        This circuit has a function that is unknown.

• Determine the output voltage, V_out, in terms of all of the resistors as shown.  Note that the feedback resistors (R_f) are the same for the two op amps.
• V_out = ___________________________
• Compute the output voltage for these values.  Your result will contain symbolic values for the voltages.
• R_f = 10,000W
• R_a = 5,000W
• R_b  = 10,000W
• R_c  = 20,000W
• V_out = ___________________________
