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 LTC4070E is guaranteed to meet performance specifications
for junction temperatures from 0°C to 85°C. Specifications over the –40°C
to 85°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC4070I is guaranteed over the full –40°C to 125°C operating junction
temperature range. Note that the maximum ambient temperature is
determined by specific operating conditions in conjunction with board
layout, the rated package thermal resistance and other environmental
