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 and LT1490AI are guaranteed functional over the
operating temperature range of – 40 C to 85 C.
Note 4: The LT1490AC is guaranteed to meet specified performance from
0 C to 70 C. The LT1490AC is designed, characterized and expected to
meet specified performance from – 40 C to 85 C but is not tested or QA
sampled at these temperatures. The LT1490I is guaranteed to meet
specified performance from –40 C to 85 C.

Note 5: ESD (Electrostatic Discharge) sensitive device. Extensive use of
ESD protection devices are used internal to the LT1490A. However, high
electrostatic discharge can damage or degrade the device. Use proper
ESD handling precautions.
