Notes:

(1)

Typical value is based on the Vio drift observed after 1000 h at 125 °C extrapolated to 25 °C using the Arrhenius law and

assuming an activation energy of 0.7 eV. The operational amplifier is aged in follower mode configuration (see Section 5.5: "Long

term input offset voltage drift").
