Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: These parameters are guaranteed by design. Thermocouple effects
preclude measurements of these voltage levels during automated testing.
Note 3: All versions of the LTC2050 are designed, characterized and
expected to meet the extended temperature limits of –40°C and 125°C.
The LTC2050C/LTC2050HVC are guaranteed to meet the temperature limits
of 0°C and 70°C. The LTC2050I/LTC2050HVI are guaranteed to meet the
temperature limits of –40°C and 85°C. The LTC2050H/LTC2050HVH are
guaranteed to meet the temperature limits of –40°C and 125°C.
Note 4: The bias current measurement accuracy depends on the proximity
of the supply bypass capacitor to the device under test, especially at ±5V
supplies. Because of testing limitations on the placement of this bypass
capacitor, the bias current at ±5V supplies is guaranteed by design to meet
the data sheet limits, but tested to relaxed limits.
