UA741CPSR from Texas Instruments, in a SO-8-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OFFSET N1 | input | External input offset voltage adjustment pin, used together with OFFSET N2 to null the input offset voltage; the datasheet gives no adjustment range or circuit for this pin. |
| 2 | IN- | input | Inverting input of the operational amplifier. |
| 3 | IN+ | input | Non-inverting input of the operational amplifier; input voltage must not exceed the supply voltage magnitude or 15 V, whichever is smaller. |
| 4 | VCC- | power_in | Negative supply; recommended range -5 V to -15 V, absolute maximum supply voltage ±18 V. |
| 5 | OFFSET N2 | input | External input offset voltage adjustment pin, used together with OFFSET N1 to null the input offset voltage; the datasheet gives no adjustment range or circuit for this pin. |
| 6 | OUT | output | Amplifier output, which may be shorted to ground or either supply with indefinite duration per the absolute maximum ratings. |
| 7 | VCC+ | power_in | Positive supply; recommended range 5 V to 15 V, absolute maximum supply voltage ±18 V. |
| 8 | NC | unconnected | No internal connection; pin is not connected internally. |
