**Texas Instruments** · FET Input Amplifiers · SOIC-8

TL081ACDR 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. |
| 2 | IN- | input | Inverting input; common-mode voltage range (VCC-) - 0.5 to (VCC+) + 0.5 V per absolute maximum ratings. |
| 3 | IN+ | input | Non-inverting input; common-mode voltage range (VCC-) - 0.5 to (VCC+) + 0.5 V per absolute maximum ratings. |
| 4 | VCC- | power_in | Negative power supply connection for dual-supply or ground reference for single-supply operation. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Output terminal of the operational amplifier. |
| 7 | VCC+ | power_in | Positive power supply connection; operates with 4.5 V to 40 V total supply voltage between VCC+ and VCC- for this device variant. |
| 8 | NC | unconnected | No internal connection. |
