A requirement exists for an OPAMP circuit with the input-output relationship vO 5vS1 2vS2 Two proposed

A requirement exists for an OPAMP circuit with the input-output relationship vO ¼ 5vS1 2vS2 Two proposed designs are shown in Figure P4–65. As the project engineer, you must recommend one of these circuits for production. Which of these circuits would you recommend for production and why? Hint: First, verify that the circuits perform the required function.
