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 specifi cations
from 0°C to 125°C internal. Specifi cations over the –40°C to 125°C
internal temperature range are assured by design, characterization and
correlation with statistical process controls. LTM8032I is guaranteed

over the full –55°C to 125°C internal operating temperature range. Note
that the maximum internal temperature is determined by specifi c operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
