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 LTM8020E is guaranteed to meet performance specifications

from 0°C to 85°C ambient. Specifications over the full –40°C to

85°C ambient operating temperature range are assured by design,

characterization and correlation with statistical process controls. The

LTM8020I is guaranteed to meet specifications over the full –40°C to 85°C

ambient operating temperature range. The LTM8020MP 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.

Note 3: Guaranteed by design.
