ELECTRICAL CHARACTERISTICS Note 7:
Input common mode range is tested by testing at both VICM = 1.25V Effects of Resistor Pair Mismatch in the Applications Information section and at the Electrical Characteristics table limits to verify that the differential of this data sheet). For a better indicator of actual amplifier performance offset (VOSDIFF) and the common mode offset (VOSCM) have not deviated by independent of feedback component matching, refer to the PSRR more than ±1mV and ±2mV respectively from the VICM = 1.25V case. specification. The voltage range for the output common mode range is tested by
Note 9:
Differential power supply rejection (PSRR) is defined as the ratio applying a voltage on the VOCM pin and testing at both VOCM = 1.25V and of the change in supply voltage to the change in differential input referred at the Electrical Characteristics table limits to verify that the common offset voltage. Common mode power supply rejection (PSRRCM) is mode offset (VOSCM) has not deviated by more than ±6mV from the defined as the ratio of the change in supply voltage to the change in the VOCM = 1.25V case. output common mode offset voltage.

Supply voltage range is guaranteed by power supply rejection common mode voltage at the pins +IN or –IN to the change in differential ratio test. input referred offset voltage. Output CMRR is defined as the ratio of
Note 11:
Extended operation with the output shorted may cause the the change in the voltage at the VOCM pin to the change in differential junction temperature to exceed the 150°C limit. input referred offset voltage. This specification is strongly dependent on
