LT1497 temperature range

harci
on Apr 22, 2018

Hi...

I want to use LT1497 for negative temperature range. Is there a model of this component that can work in the negative temperature range without problems? Thanks

    Note 2 in the data sheets says "The LT1497 is designed, characterized and expected to operate over the temperature range of –40°C to 85°C, but is not tested at –40°C and 85°C. "   The LT1497 is 100% production tested at 25C to all the min/max specs in the datasheet unless otherwise stated.  It is sample tested at 0C and 70C, with a single failure requiring testing the entire lot.   It can definitely be used in industrial applications, but may violate some specs if the temperature range exceeds the 0-70C range.   Note 2 added "Guaranteed industrial grade parts are available, consult factory" but it seems we never finalized an "I grade" version.

    As Gauzz mentioned, there are quite a few plots in the data sheet showing typical behavior from -50C to 125C.

    Hope this helps, Glen.
