LM741N from HGSEMI, in a DIP-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 | OFFSET NULL | passive | Offset null terminal; a 10 kΩ potentiometer to V- between pins 1 and 5 trims input offset voltage. |
| 2 | INVERTING INPUT | input | Inverting input; absolute maximum input voltage ±15V (equal to supply if supply is below ±15V), differential input ±30V. |
| 3 | NON-INVERTING INPUT | input | Non-inverting input; absolute maximum input voltage ±15V (equal to supply if supply is below ±15V), differential input ±30V. |
| 4 | V- | power_in | Negative supply pin; supply voltage absolute maximum ±18V total span, and the offset-null potentiometer wiper connects here. |
| 5 | OFFSET NULL | passive | Offset null terminal; connects to the other end of the 10 kΩ offset-nulling potentiometer with pin 1. |
| 6 | OUTPUT | output | Amplifier output with continuous short-circuit protection; typical short-circuit current 25 mA at 25°C. |
| 7 | V+ | power_in | Positive supply pin; supply voltage absolute maximum ±18V. |
| 8 | NC | unconnected | No internal connection. |
