OPA191的问题

Part Number: OPA191
Other Parts Discussed in Thread: OPA171,

我的操作步骤如下:

1.打开官网,下载了如下这个参考模型;

OPAx191 PSpice Model (Rev. B)

2.打开PSpice for TI这个软件,如下在如下处加入仿真点,点击仿真按钮,就会报WARNING(ORPSIM-15188): There are no devices in this circuit这个错误,也不知道啥原因,但是下载OPA171这个模型仿真就没有问题,

如下是我画的OPA191的原理图,你能帮我仿真一下吗?给出仿真结果,我这边需要用到这个OPA191这个运放,谢谢
