The inputs of the op-amp must stay within a certain voltage range for proper operation. Each of the two input pins of the op-amp has voltage swing restrictions, beyond which the op-amp will not work correctly or will behave non-linearly. Non-linearity means that aside from a change in the signal's amplitude, the information contained in the signal is changed and new information is introduced.

Figure 2 shows an example from the MCP602 datasheet.
