±15V ELECTRICAL CHARACTERISTICS

The

G = 1, 10, unless otherwise noted. (Notes 4, 6)

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: ESD (Electrostatic Discharge) sensitive device. Extensive use of

ESD protection devices are used internal to the LT1990, however, high

electrostatic discharge can damage or degrade the device. Use proper ESD

handling precautions.

Note 3: A heat sink may be required to keep the junction temperature

below absolute maximum.

Note 4: The LT1990C/LT1990I are guaranteed functional over the

operating temperature range of – 40

°C to 85°C. The LT1990H is

guaranteed functional over the operating temperature range of –40

°C

to 125

°C.

Note 5: The LT1990C is guaranteed to meet the specified performance

from 0

°C to70°C and 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 LT1990I is guaranteed to meet

specified performance from –40

°C to 85°C. The LT1990H is guaranteed to

meet specified performance from –40

°C to 125°C.

Note 6: G = 10 limits are guaranteed by correlation to G = 1 tests and gain

error tests at G = 10.

Note 7: Limits are guaranteed by correlation to –5V to 80V CMRR tests.

Note 10: This parameter is not 100% tested.

Note 11: Hysteresis in offset voltage is created by package stress that

differs depending on whether the IC was previously at a higher or lower

temperature. Offset voltage hysteresis is always measured at 25

°C, but the

IC is cycled to 85

°C I-grade (70°C C-grade or 125°C H-grade) or –40°C

I/H-grade (0

°C C-grade) before successive measurement.
