G1=60µV, G2=10µV. What is the output signal volatage?

• A. 50µV
• B. -50µV
• C. -70µV
• D. 70µV

Answer: (A)

The output comes from the difference between the two input signals in a differential or subtractor setup. With G1 = 60 µV and G2 = 10 µV, you subtract the second from the first: 60 µV − 10 µV = 50 µV. Since the higher input is on the non-inverting side in this orientation, the result is positive. So the output signal voltage is 50 µV. The other values would correspond to different relationships (for example, adding the inputs would give 70 µV, or swapping inputs would yield −50 µV).
