zxcvb Posted September 27, 2021 Posted September 27, 2021 I bought a LM3900 Op-amp after reading a detailed introduction article about this device, here's the link: LM3900 datasheet. It gives me their comparison about specifications. But I found that the only difference between them is output current. So I have a question: can these two be used interchangeably even their output current is different? I’m not the expert at Op-amp, any help will be appreciated.
