The denotes specifications which apply over the full operating
temperature range.
Note 1: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage
and how many amplifiers are shorted.
Note 2: The LT1490/LT1491 are designed, characterized and expected
to meet these extended temperature limits, but are not tested at – 40 C
and 85 C. Guaranteed I grade parts are available, consult factory.
