The q 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.
Note 3: VS = 5V limits are guaranteed by correlation to VS = 3V and
VS = ±15V tests.
Note 4: VS = 3V limits are guaranteed by correlation to VS = 5V and
VS = ±15V tests.
Note 5: Guaranteed by correlation to slew rate at VS = ±15V and GBW
at VS = 3V and VS = ±15V tests.
Note 6: This parameter is not 100% tested.
