arduino - Can I use an op-amp to supply itself a negative voltage? - Electrical Engineering Stack Ex
For my project, I am using an LM324. According to the datasheet, its power supply can either be +/- 16V or 0-32V (max). The output will range from -3V to +3V (or there abouts), so I realise I'm goi... ... You can generate a negative voltage with a small c...
