† Data applies for the amplifier block only; the switched-capacitor block is not supplying VCC – supply.
‡ Full range is – 40°C to 85°C.
NOTE 6: Typical values are based on the input offset voltage shift observed through 168 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.
