请问若要测试一运放的Slew Rate时要接负载吗?我在国外的某网站有个帖子是这样说的:
Settling time is electrical parameter of opa under small signal, but the slew rate is electrical parameter of opa under large signal. I think they both have no relation. (这里他应该说错了吧?!做Settling time 测试也应该使用附中大信号输入的吧?)
When simulating in and do transient analysis, then plot the out wave(of course,under the load u defined). at last, measure the slope of out voltage linear ramp, it is slew rate.
我不明白的是红色标注的部分。究竟要不要接上自己定义的负载才仿真呢?SR指标是不是在某一负载的条件下的?类似的问题,测试Settling time时 要不要接上负载呢?
