These TI LMV358 opamps have a maximum V+/V- voltage of 5.5 Volts. Which means V+ max = 5.5V if V- is GND, or ±2.75 Volts in a bipolar config. But you're feeding them ±12 Volts? Have I missed something? Has v6.5.1 actually been manufactured yet? <img width="1062" height="578" alt="Image" src="https://github.com/user-attachments/assets/e085dce9-b513-4d8b-9309-89cd100736bf" />
