REF1112: Operating Temp Range

Part Number: REF1112

Hi Reference Team,

I'm reaching out about the REF1112 and it's operating range. In the datasheet it makes the statement:

"The REF1112 is specified from –40°C to +85°C with operation extending from –40°C to +125°C."

What does this mean?

Maybe a better question, what temp range do we actually test to?

There are 3 different ranges throughout the datasheet, the operating range in the orderable parts section clearly notes only up to 85:

While the recommended temp range is up to 125:

To add to this, the abs max temp rating is down to -55C:

Thank you.
