CMRR

The ability of an amplifier to amplify a signal in the presence of electrical noise. The higher the number, the better the amplification.

These parts feature a high common mode rejection ratio, power supply rejection ratio, and high open loop gain, all in excess of 120 dB.
With a low input offset voltage of 100 [mu]V max., low input offset drift of less than 0.5 [mu]V/[degrees]C, a high power supply rejection and common mode rejection ratio of 100 dB min., the amplifier keeps DC errors to a minimum and eliminates the need for external trim circuitry.
This also results in high power supply and common mode rejection ratios.
