An op-amp has open-loop DC gain of 100000. If the differential input voltage is 50 microvolts and the output is not saturated, the open-loop output would be approximately?

  • A0.5 V
  • B5 V
  • C50 V
  • D500 V
Report an error
Correct Answer: B. 5 V
Explanation: Vo=Aol(V+-V-)=100000×50 microvolts=5 V.
Reference: Standard analog electronics: open-loop gain
