Hi,
As I looked through the latest datasheet of XTR116 (SBOS124B – JANUARY 2000 – REVISED JUNE 2023) , the minimum operating temperature has been changed from -55C to -40C. I'm pleased to know if the construction of the IC has been changed from the former configuration such that -55 C operation is compromised. This is because we are using this part in few main stream aerospace products which are rated to -55C.
Thanks,
Kavindu
