以下是手册描述，问题是LTM4622AE和LTM4622AI区别是什么
The LTM4622A is tested under pulsed load conditions such that
TJ ≈ TA. The LTM4622AE is guaranteed to meet performance specifications
over the 0°C to 125°C internal operating temperature range. Specifications
over the full –40°C to 125°C internal operating temperature range are
assured by design, characterization and correlation with statistical process
controls. The LTM4622AI is guaranteed to meet specifications over the
full –40°C to 125°C internal operating temperature range. Note that the
maximum ambient temperature consistent with these specifications
is determined by specific operating conditions in conjunction
with board layout, the rated package thermal resistance and other
environmental factors.
