CMRR and Slew rate: These terms are closely related but have different meanings.
CMRR: Stands for Common Mode Rejection Rate. It describes how well an op-amp rejects unwanted input signals that appear at its input terminals while working with a constant output voltage. Basically, it tells us how well the op-amp isolates the input signal from the output signal.
Slew rate: This refers to the rate at which the output voltage of an op-amp changes with respect to the input voltage. It is measured in units of volts per second and tells us how quickly the output voltage transitions between its positive and negative supply voltages.
Here's an analogy to help differentiate between them:
Think of a microphone as an op-amp. When you speak into the microphone, the sound waves cause the diaphragm to move, which changes the output voltage. The op-amp acts as a filter, blocking out unwanted background noise while amplifying the sound of your voice.
Similarly, the slew rate tells us how quickly the op-amp changes its output voltage in response to changes in the input voltage. A high slew rate means the op-amp changes output voltage rapidly, while a low slew rate means it changes it more slowly
