LT6600-5 extended temperature range


we intend to use the LT6600-5 in a design where we need extended temperature range (-40°C to 105°C, preferably -40°C to 125°C). Device to be used as input amplifier for LTC2246H which is specified for -40°C to 125°C.

Datasheet says "Consult LTC Marketing for parts specified with wider operating temperature ranges."

Is there a version of the LT6600-5 available with temperature range beyond the "I" version -40°C to 85°C? Is there performance data available for operating the device above 85°C?

Thank You & Regards,
