ELECTRICAL CHARACTERISTICS

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 LTM8021E is guaranteed to meet performance specifications

from 0°C to 125°C internal. Specifications over the full –40°C to 125°C

internal operating temperature range are assured by design, characteriza-

The

tion and correlation with statistical process controls. The LTM8021I is

guaranteed to meet specifications over the full –40°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.

Note 3: Guaranteed by design.
