For an ideal op-amp comparator with V+ greater than V-, the output tends toward?

  • AThe positive saturation level
  • BThe negative saturation level
  • CExactly zero in all cases
  • DThe input common-mode voltage
Report an error
Correct Answer: A. The positive saturation level
Explanation: With no linear negative feedback, an ideal comparator drives its output toward positive saturation when the non-inverting input exceeds the inverting input.
Reference: Standard analog electronics: comparator
