TL031CDR 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 | Not connected. |
| 2 | IN- | input | Inverting input; the input voltage must not exceed the supply magnitude or 15 V, whichever is smaller, and the input current is limited to ±1 mA per input (absolute maximum ratings). |
| 3 | IN+ | input | Non-inverting input; the same input voltage limit (supply magnitude or 15 V, whichever is smaller) and ±1 mA input current limit apply as for IN-. |
| 4 | VCC- | power_in | Negative power supply; absolute maximum is -18 V and recommended operation is ±5 V to ±15 V. |
| 5 | NC | unconnected | Not connected. |
| 6 | OUT | output | Output; maximum output current is ±40 mA per output, and the output may be shorted to either supply, although prolonged short circuits at higher supply voltages can cause overheating and eventual destruction. |
| 7 | VCC+ | power_in | Positive power supply; absolute maximum is 18 V and recommended operation is ±5 V to ±15 V. |
| 8 | NC | unconnected | Not connected. |
