ELECTRICAL CHARACTERISTICS
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: The LTC2054/LTC2055 are designed, characterized and expected to
meet the extended temperature limits of –40°C and 125°C. The LTC2054C/
LTC2055C/LTC2054HVC/LTC2055HVC are guaranteed to meet the
temperature limits of 0°C and 70°C. The LTC2054I/LTC2055I/LTC2054HVI/
LTC2055HVI are guaranteed to meet temperature limits of –40°C and
85°C. The LTC2054H/LTC2055H and LTC2054HVH/LTC2055HVH are
guaranteed to meet the temperature limits of –40°C and 125°C. The
LTC2054MP/LTC2054HVMP are guaranteed to meet the temperature limits
of –55°C and 150°C.
Note 3: These parameters are guaranteed by design. Thermocouple effects
preclude measurements of these voltage levels during automated testing.
Note 4: Limit is determined by high speed automated test capability. See
Typical Characteristic curves for actual typical performance. For tighter
specications, please consult Linear Technology Marketing.
Note 5: The θJA specied for the DD package is with minimal PCB heat
spreading metal. Using expanded metal area on all layers of a board
reduces this value.
