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 LTM8032E is guaranteed to meet performance specifications 
from 0°C to 125°C internal. Specifications over the –40°C to 125°C 
internal temperature range are assured by design, characterization and

correlation with statistical process controls. LTM8032I is guaranteed 
to meet specifications over the full –40°C to 125°C internal operating 
temperature range. The LTM8032MP is guaranteed to meet specifications 
over the full –55°C to 125°C internal operating temperature range. Note 
that the maximum internal temperature is determined by specific operating 
conditions in conjunction with board layout, the rated package thermal 
resistance and other environmental factors.
