Note 1:
Stresses beyond those listed under Absolute Maximum Ratings are guaranteed to meet the temperature limits of – 40°C and 125°C. may cause permanent damage to the device. Exposure to any Absolute
Note 4:
The bias current measurement accuracy depends on the proximity of Maximum Rating condition for extended periods may affect device the negative supply bypass capacitors to the device under test. Because of reliability and lifetime. this, only the bias current of channel B (LTC2051) and channels A and B
Note 2:
These parameters are guaranteed by design. Thermocouple effects (LTC2052) are 100% tested to the data sheet specifications. The bias preclude measurements of these voltage levels during automated testing. currents of the remaining channels are 100% tested to relaxed limits,
Note 3:
All versions of the LTC2051/LTC2052 are designed, characterized however, their values are guaranteed by design to meet the data sheet limits. and expected to meet the extended temperature limits of – 40°C and 125°C.
Note 5:
This parameter is guaranteed to meet specified performance The LTC2051C/LTC2052C/LTC2051HVC/LTC2052HVC are guaranteed to through design and characterization. It has not been tested. meet the temperature limits of 0°C and 70°C. The LTC2051I/LTC2052I/
Note 6:
The θJA specified for the DD package is with minimal PCB heat LTC2051HVI/LTC2052HVI are guaranteed to meet temperature limits of – spreading metal. Using expanded metal area on all layers of a board 40°C and 85°C. The LTC2051H/LTC2051HVH and LTC2052H/LTC2052HVH reduces this value. 20512fd 5
