您好， 感谢您对TI产品的关注！ .ckt文件您是在哪里下载的呢，据我了解的信息，TI应该没有提供OPA211的.ckt文件，根据这个网页（https://www.fileviewpro.com/zh-cn/file-extension-ckt）描述，.ckt应该是Altium公司开发的文件，您可以寻求Altium公司的支持 抱歉，关于.ckt文件问题无法给您提供帮助，如果您在使用OPA211设计电路时遇到问题，您可以发帖，我们可以一起讨论解决

ckt文件是我在TI官网OPA211芯片下的设计工具和仿真里下载的Spice模型（sbom307e或sboc250c内的OPA211.lib文件我把更改扩展名为.ckt）
按照文件前面的介绍，应该是可以适用的

一般的话，这种Spice模型文件直接改为ckt扩展名是可以用的，其他TI芯片的仿真模型也是可以这么用的
