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 LTC2051/LTC2052 are designed, characterized
and expected to meet the extended temperature limits of –40°C and 125°C.
The LTC2051C/LTC2052C/LTC2051HVC/LTC2052HVC are guaranteed to
meet the temperature limits of 0°C and 70°C. The LTC2051I/LTC2052I/
LTC2051HVI/LTC2052HVI are guaranteed to meet temperature limits of –
40°C and 85°C. The LTC2051H/LTC2051HVH and LTC2052H/LTC2052HVH
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 negative supply bypass capacitors to the device under test. Because of
this, only the bias current of channel B (LTC2051) and channels A and B
(LTC2052) are 100% tested to the data sheet specifications. The bias
currents of the remaining channels are 100% tested to relaxed limits,
however, their values are guaranteed by design to meet the data sheet limits.
Note 5: This parameter is guaranteed to meet specified performance
through design and characterization. It has not been tested.
Note 6: The θJA specified for the DD package is with minimal PCB heat
spreading metal. Using expanded metal area on all layers of a board
reduces this value.
