With zero volts on both inputs, an OP-amp ideally should have an output _______________?
Correct answer: C. equal to zero
- A. equal to the positive supply voltage
- B. equal to the negative supply voltage
- C. equal to zero
- D. equal to CMRR
Explanation
With equal zero-voltage inputs, the ideal differential input voltage is zero, so the ideal op-amp output is also zero. Any nonzero output in a practical device is caused by offset voltage, bias currents, or other imperfections.
