Note 1:
Absolute Maximum Ratings are those values beyond which the
life of the device may be impaired.
Note 2:
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 3:
The LT1490C/LT1491C are guaranteed to meet specified
performance from 0
°
C to 70
°
C. The LT1490C/LT1491C are designed,
characterized and expected to meet specified performance from –40
°
C
to 85
°
C but are not tested or QA sampled at these temperatures.
The LT1490I/LT1491I are guaranteed to meet specified performance from
–40
°
C to 85
°
C.
