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 LTM8025E is guaranteed to meet performance specifi cations
from 0°C to 125°C internal. Specifi cations over the full –40°C to
125°C internal operating temperature range are assured by design,

characterization and correlation with statistical process controls. The
LTM8025I is guaranteed to meet specifi cations over the full –40°C
to 125°C internal operating temperature range. The LTM8025MP is
guaranteed to meet specifi cations 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.
