Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4
: The LT1468C is guaranteed to meet specifi ed performance from may cause permanent damage to the device. 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. Input voltages outside the supplies will
Note 6
: Full power bandwidth is calculated from the slew rate be clamped by ESD protection devices and input currents should also be measurement: FPBW = SR/2πVP limited to 10mA.
Note 7
: This parameter is not 100% tested.
Note 3
: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefi nitely. 1468fb 5
