It is on page 3 of datasheet:about ambient temperature performance
Note 3: The LTC3419E and LTC3419E-1 are guaranteed to meet specifi ed performance from 0°C to 85°C. Specifi cations over the –40°C to 125°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. The LTC3419I and LTC3419I-1 are guaranteed to meet specifi ed performance over the full –40°C to 125°C operating junction temperature range.
