Notes:

9. Limits over the full temperature are guaranteed by design, but not tested in production.

10. After mounted to PCB, Vos value will be different to spec, the delta value depend on PCB solder stress, the max value is between +/- 80µV, per our

experiment.

11. AS2376Q, the long-term stability is defined as MAX. Vos shift during life HTOL 1000 hours with TA=+125°C (Tj=150°C). This Vos drift with time is not a

linear function of time, and the shift is greater initially and diminishes over time. This parameter is guaranteed by design.

12. After HTSL 2000 hours with TA=+150°C, the Vos drift test condition is TA=+125°C.
