Как проверить операционный усилитель ( ОУ) при помощи Цифрового Мультиметра

We periodically encounter operational amplifiers in amateur radio practice, as well as during electronics repair. Many people know what they are, how they work, and what functions they perform. But the topic of today's video is different. How do you test an operational amplifier? It should be as simple as possible. And preferably with a regular multimeter. Digital or pointer, which every radio amateur has.
