ELECTRICAL CHARACTERISTICS

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

°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.

Note 6: VS = 5V limits are guaranteed by correlation to VS = 3V and

VS = ±15V tests.

Note 7: VS = 3V limits are guaranteed by correlation to VS = 5V and

VS = ±15V tests.

Note 8: Guaranteed by correlation to slew rate at VS = ±15V and GBW

at VS = 3V and VS = ±15V tests.

Note 9: This parameter is not 100% tested.

The q denotes specifications which apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. VS = ±15V unless otherwise noted. (Note 4)
