LM833DR2G from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Output of op-amp channel 1. Low-impedance analog output capable of driving typical audio loads. |
| 2 | IN1- | input | Inverting input of op-amp channel 1. High-impedance analog input. |
| 3 | IN1+ | input | Non-inverting input of op-amp channel 1. High-impedance analog input. |
| 4 | VEE | power_in | Negative supply rail. Typically connected to a negative supply for split-supply operation or to GND for single-supply operation. Supply range ±5 V to ±18 V (total 10 V to 36 V). |
| 5 | IN2+ | input | Non-inverting input of op-amp channel 2. High-impedance analog input. |
| 6 | IN2- | input | Inverting input of op-amp channel 2. High-impedance analog input. |
| 7 | OUT2 | output | Output of op-amp channel 2. Low-impedance analog output capable of driving typical audio loads. |
| 8 | VCC | power_in | Positive supply rail. Supply range ±5 V to ±18 V (total 10 V to 36 V). |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
lm833dr2g.step |
122 KB | You want the bare part, or you mark your own boards. |

2.2 MB | You want the part with LM833DR2G already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 540 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
