denotes specifications which apply over the full operating temperature
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 LT1490AC/LT1491AC and LT1490AI/LT1491AI are guaranteed
functional over the operating temperature range of –40
°
C to 85
°
C. The
LT1490AH/LT1491AH are guaranteed functional over the operating
temperature range of –40
°
C to 125
°
C.
Note 4:
The LT1490AC/LT1491AC are guaranteed to meet specified
performance from 0
°
C to 70
°
C. The LT1490AC/LT1491AC are designed,
characterized and expected to meet specified performance from –40
°
C to

°
C but are not tested or QA sampled at these temperatures. The
LT1490AI/LT1491AI are guaranteed to meet specified performance from
–40
°
C to 85
°
C. The LT1490AH/LT1491AH are guaranteed to meet
specified performance from –40
°
C to 125
°
C.
Note 5:
ESD (Electrostatic Discharge) sensitive device. Extensive use of
ESD protection devices are used internal to the LT1490A/LT1491A.
However, high electrostatic discharge can damage or degrade the device.
Use proper ESD handling precautions.
