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.

AE:在0~125°能正常工作,AI:在-40~125°都可以正常工作,看你自己选择,假如产品需要在特殊环境中用那就选AI。

你既然能粘贴,那就应该能找个翻译软件

如果你有英语阅读能力,那你应该可以注意到差异
