*9 Instantaneous common mode rejection voltage “ output (1) “ represents

a common mode voltage variation that can hold the output above (1) level ( Vo > 2.0V )

*10 Instantaneous common mode rejection voltage “ output (0) “ represents

a common mode voltage variation that can hold the output above (0) level ( Vo < 0.8V )
