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 specifications
Note 2: The LTM8032E is guaranteed to meet performance specifications

correlation with statistical process controls. LTM8032I is guaranteed
to meet specifications over the full –40°C to 125°C internal operating
temperature range. The LTM8032MP 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.
