Note 1:
Stresses beyond those listed under Absolute Maximum Ratings correlation with statistical process controls. LTM8032I is guaranteed may cause permanent damage to the device. Exposure to any Absolute to meet specifications over the full –40°C to 125°C internal operating Maximum Rating condition for extended periods may affect device temperature range. The LTM8032MP is guaranteed to meet specifications reliability and lifetime. over the full –55°C to 125°C internal operating temperature range. Note
Note 2:
The LTM8032E is guaranteed to meet performance specifications that the maximum internal temperature is determined by specific operating from 0°C to 125°C internal. Specifications over the –40°C to 125°C conditions in conjunction with board layout, the rated package thermal internal temperature range are assured by design, characterization and resistance and other environmental factors. 8032fg For more information www.linear.com/LTM8032 3 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Operation Applications Information Typical Applications Package Description Revision History Package Photographs Related Parts
