=> RiF= 6.67 MΩ. 6. Find the type of amplifier that cannot be constructed in differential configuration?
A. Summing amplifier
B. Scaling amplifier
C. Averaging amplifier
D. Subtractor
Answer:A
=> RiF= 6.67 MΩ. 6. Find the type of amplifier that cannot be constructed in differential configuration?
A. Summing amplifier B. Scaling amplifier C. Averaging amplifier D. Subtractor
Explanation: In differential op-amp configuration, an amplifier produces sum or difference between two input terminals of op-amp. So, averaging is not possible in this type of configuration. 7. Calculate the output voltage, when a voltage of 12mv is applied to the non-inverting terminal and 7mv is applied to inverting terminal of a subtractor.
