Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
The LT1990I-10 is guaranteed to meet specified performance from may cause permanent damage to the device. Exposure to any Absolute –40°C to 85°C. Maximum Rating condition for extended periods may affect device
Note 6:
Limits are guaranteed by correlation to –5V to 80V CMRR tests. reliability and lifetime.
Note 7:
VS = 3V limits are guaranteed by correlation to VS = 5V and
Note 2:
ESD (Electrostatic Discharge) sensitive device. Extensive use of VS = ±15V tests. ESD protection devices are used internal to the LT1990-10, however, high
Note 8:
V electrostatic discharge can damage or degrade the device. Use proper ESD S = 5V limits are guaranteed by correlation to VS = 3V and V handling precautions. S = ±15V tests.
Note 9:
This parameter is not 100% tested.
Note 3:
A heat sink may be required to keep the junction temperature below absolute maximum.
Note 10:
Hysteresis in offset voltage is created by package stress that differs depending on whether the IC was previously at a higher or lower
Note 4:
The LT1990I-10 is designed, characterized and expected to be temperature. Offset voltage hysteresis is always measured at 25°C, but the functional over the operating temperature range of –55°C to 125°C, but is IC is cycled to 85°C or –40°C before successive measurement. not tested or QA sampled at these temperatures.
