Note 4:
The LT1880C and LT1880I are guaranteed functional over the may cause permanent damage to the device. Exposure to any Absolute operating temperature range of –40°C to 85°C. Maximum Rating condition for extended periods may affect device
Note 5:
The LT1880C is guaranteed to meet specifi ed performance from reliability and lifetime. 0°C to 70°C and is designed, characterized and expected to meet specifi ed
Note 2:
The inputs are protected by back-to-back diodes. If the differential performance from –40°C to 85°C but is not tested or QA sampled at these input voltage exceeds 10V, see Application Information, the input current temperatures. The LT1880I is guaranteed to meet specifi ed performance should be limited to less than 10mA. from –40°C to 85°C.
