Then you could use a common op amp such as the LM358 which has a possible common mode input range to within 1.5V of the positive supply. Also the LM358's output will swing between the negative supply and to within 1.5V of the positive supply. | |

| Jan 27, 2020 at 14:19 | comment | added | v3xX | Yes. I tried to scale the problem from 30V->3V since I can not find compatible devices in the MINDI library | |
