The op-amp can operate in both the differential mode or the common mode. 4. Common-mode rejection means that a signal appearing on both inputs is effectively cancelled. 5. CMRR stands for common-mode rejection reference. 6. Slew rate determines how fast the output can change in response to a step input. 7. Negative feedback reduces the gain of an op-amp from its open-loop value. 8. Negative feedback reduces the bandwidth of an op-amp from its open-loop value. 9. A noninverting amplifier uses negative feedback. 10. The gain of a voltage-follower is very high. 11. Negative feedback affects the input and output impedances of an op-amp. 12. A compensated op-amp has a gain roll-off of -20 dB/decade above the critical frequency. 13. The gain-bandwidth product equals the unity-gain frequency. 14. If the feedback resistor in an inverting amplifier opens, the gain becomes zero.
