UA741CDR from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No internal connection; leave unconnected. |
| 2 | IN- | input | Inverting differential input accepts signals with maximum input voltage rating of ±15 V. |
| 3 | IN+ | input | Non-inverting differential input accepts signals with maximum input voltage rating of ±15 V. |
| 4 | VCC- | power_in | Negative power supply with recommended operating range from −5 V to −15 V. |
| 5 | NC | unconnected | No internal connection; leave unconnected. |
| 6 | OUT | output | Analog output delivers maximum peak voltage swing of ±10 V to ±14.95 V depending on load resistance. |
| 7 | VCC+ | power_in | Positive power supply with recommended operating range from 5 V to 15 V. |
| 8 | NC | unconnected | No internal connection; leave unconnected. |
