Standard 8-Pin Dual Op-Amp (e.g., TL072, LM358)

1. Output A
2. Inverting Input A
3. Non-Inverting Input A
4. V- (Negative Supply / GND)
5. Non-Inverting Input B
6. Inverting Input B
7. Output B
8. V+ (Positive Supply)

Note: Always check the specific datasheet, as 'Single' op-amps (like the LM741) use a completely different pinout.
