Notes:

(1)

Maximum values are guaranteed by design.

(2)

Typical value is based on the Vio drift observed after 1000h 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 4.6).
