Explanation: Output voltage of a subtractor Vo = Vnon-inverting terminal – Vinverting terminal = 12mv-7mv =5mv. 8. In differential op-amp configuration a subtractor is called as
A. Summing amplifier
B. All of the mentioned
C. Scaling amplifier
D. Difference amplifier
Answer:A
Explanation: Output voltage of a subtractor Vo = Vnon-inverting terminal – Vinverting terminal = 12mv-7mv =5mv. 8. In differential op-amp configuration a subtractor is called as
A. Summing amplifier B. All of the mentioned C. Scaling amplifier D. Difference amplifier
Explanation: In a subtractor input signals can be scaled to the desired values by selecting appropriate values for the external resistors. Therefore, this circuit is referred to as scaling amplifier. 9. Find the differential amplifier configured as a subtractor from the given circuit.
