Be aware in a microcontroller design, an lm324-type op amp might outperform the on-chip ADC you’re using anyway. Even the cheapest op amps from major players are better characterized and specified on their data sheets than most microcontroller ADCs. There’s no virtue in spending other people’s money and supply chain risk to use a “better” part just because it wins a bench race or it’s newer or whatever.
- pythonguython 2y agoWhat does it mean for an op amp to outperform an ADC?
- buescher 2y agoIt can have wider bandwidth, lower noise+distortion, smaller Vos, maybe other things I'm not recalling off the top of my head. In practical terms, you might not be able to run any test with the ADC that can find the limits of the op amp.
