denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. V+ = 5V, V– = 0V, VCM = VOCM = VICM = 2.5V, VSHDN = open. VS is defined as (V+ – V–). VOUTCM is defined as (V+OUT + V–OUT)/2. VICM is defined as (V+IN + V–IN)/2. VOUTDIFF is defined as (V+OUT – V–OUT). SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS

Note 9:
Input common mode range is tested by verifying that at the limits may cause permanent damage to the device. Exposure to any Absolute stated in the Electrical Characteristics table, the differential offset (VOSDIFF) Maximum Rating condition for extended periods may affect device and common mode offset (VOSCM) have not deviated by more than ±1mV reliability and lifetime. and ±35mV respectively compared to the VICM = 2.5V (at VS = 5V) and

If the inputs should exceed either supply voltage, Output common mode range is tested by verifying that at the limits stated the input current should be limited to less than 10mA. In addition, the in the Electrical Characteristics table, the common mode offset (VOSCM) inputs +IN, –IN are protected by a pair of back-to-back diodes. If the has not deviated by more than ±15mV compared to the VOCM = 2.5V differential input voltage exceeds 1.4V, the input current should be limited (at VS = 5V) and VOCM = 1.5V (at VS = 3V) cases. to less than 10mA.
