°C to 70°C. Full range for the TLV2721I is – 40°C to 85°C.

‡ Referenced to 1.5 V

NOTE 4: Typical values are based on the input offset voltage shift observed through 500 hours of operating life test at TA = 150°C extrapolated

to TA = 25°C using the Arrhenius equation and assuming an activation energy of 0.96 eV.
