For a single-pole internally compensated op-amp, the gain-bandwidth product is approximately?

  • AConstant over a useful closed-loop gain range
  • BAlways zero
  • CEqual to the supply voltage
  • DIndependent of frequency only at DC
Report an error
Correct Answer: A. Constant over a useful closed-loop gain range
Explanation: For a dominant-pole compensated op-amp, closed-loop gain multiplied by bandwidth is approximately constant over the usual operating range.
Reference: Standard analog electronics: gain-bandwidth product
