Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: These parameters are guaranteed by design. Thermocouple effects

preclude measurement of these voltage levels in high speed automatic test

capability.

Note 3: If the total source resistance is less than 10k, no DC errors result

from the input bias currents or the mismatch of the input bias currents or

the mismatch of the resistances connected to –IN and +IN.

Note 5: At temperatures above 70

°C, the common mode rejection ratio

lowers when the common mode input voltage is within 100mV of the

supply rails.

Note 6: The power supply rejection ratio (PSRR) measurement accuracy

depends on the proximity of the power supply bypass capacitor to the

device under test. Because of this, the PSRR is 100% tested to relaxed

limits at final test. However, their values are guaranteed by design to meet

the data sheet limits.
