Exposure to any Absolute 0°C to 70°C and is designed, characterized and expected to meet these Maximum Rating condition for extended periods may affect device extended temperature limits, but is not tested at – 40°C and at 85°C. The reliability and lifetime. LT1468I is guaranteed to meet the extended temperature limits. Note 2 : The inputs are protected by back-to-back diodes and two 100Ω Note 5 : Slew rate is measured between ±8V on the output with ±12V input series resistors. If the differential input voltage exceeds 0.7V, the input for ±15V supplies and ±2V on the output with ±3V input for ±5V supplies. current should be limited to 10mA.
