Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
The LT1469C is guaranteed to meet specified 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 specified Maximum Rating condition for extended periods may affect device performance from –40°C to 85°C but is not tested or QA sampled at these reliability and lifetime. temperatures. The LT1469I is guaranteed to meet specified performance
Note 2:
The inputs are protected by back-to-back diodes and two 100Ω from –40°C to 85°C. series resistors. If the differential input voltage exceeds 0.7V, the input
Note 6:
Slew rate is measured between ±8V on the output with ±12V current should be limited to less than 10mA. Input voltages outside the swing for ±15V supplies and ±2V on the output with ±3V swing for ±5V supplies will be clamped by ESD protection devices and input currents supplies. should also be limited to less than 10mA.
