Note 1:
Stresses beyond those listed under Absolute Maximum Ratings –40°C to 125°C internal operating temperature range. The LTM4606MP may cause permanent damage to the device. Exposure to any Absolute is guaranteed and tested over the –55°C to 125°C internal operating Maximum Rating condition for extended periods may affect device temperature range. Note that the maximum ambient temperature reliability and lifetime. consistent with these specifications is determined by specific operating
Note 2:
The LTM4606E is guaranteed to meet performance specifications conditions in conjunction with board layout, the rated package thermal over the 0°C to 125°C internal operating temperature range. Specifications resistance and other environmental factors. over the –40°C to 125°C internal operating temperature range are assured
Note 3:
100% tested at die level only. by design, characterization and correlation with statistical process
