TI中文支持网我在官网下载了LMH6626的spice仿真模型，发现里面只有LMH6624的模型文件。 但是LMH6624和LMH6626的噪声参数不同。问下哪里可以找到LMH6626的spice模型。
Kailyn Chen：
LMH6626主页下载的SPice模型包含了.MOD格式的LMH6624的模型，也包含了.txt格式的LMH6626的spice 模型。
您是需要LMH6626的spice 模型导入到TINA中进行仿真是吗？

您好，这个是LMH6626.txt的文件内容，看起来不像是模型文件。

TI 很多spice model都是.txt的文件。 我们可以通过PSpice Model Editor编辑器创造一个Pspice model然后把它导入到TINA中。 具体步骤可以参考这篇应用手册：

您好，这个文件不是一个spice模型，在TINA或者是Pspice上都无法使用。您能给我一个LMH6626的spice模型吗？谢谢！

回复 Bohai.Zhang:
我这边也没有.lib，.cir等的LMH6626的spice model。
您可以下载安装一个Orcad PSD，按照我上面给您的文档中介绍的步骤，使用LMH6626.txt 创建一个Pspice model。

已经了解到，没有LMH6626的模型，谢谢您了
