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 LTC4443I/LTC4443I-1 are guaranteed to meet specifications
from –40°C to 85°C. The LTC4443E/LTC4443E-1 are guaranteed to meet
specifications from 0°C to 85°C with specifications over the –40°C to
85°C operating temperature range assured by design, characterization and
correlation with statistical process controls.
