LM2902DR2G from onsemi, in a SOIC-14. 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 1. Class-AB stage; short-circuit protected to ground (Isc typ 40 mA). Output swings from VEE up to VCC-1.5 V typical. |
| 2 | IN1- | input | Inverting input of op-amp 1. High-impedance BJT input; typical input bias current -90 nA (max -250 nA at 25 °C for LM2902). |
| 3 | IN1+ | input | Non-inverting input of op-amp 1. Common-mode range extends to VEE (0 V) up to VCC-1.7 V. Absolute input voltage tolerated up to +32 V and down to -0.3 V. |
| 4 | VCC | power_in | Positive supply rail. Single-supply operation 3.0 V to 32 V, or split-supply +1.5 V to +16 V. Quiescent current typically 0.7 mA at VCC = 5 V (all four amps). |
| 5 | IN2+ | input | Non-inverting input of op-amp 2. See IN1+ for common-mode range and absolute limits. |
| 6 | IN2- | input | Inverting input of op-amp 2. Typical input bias current -90 nA. |
| 7 | OUT2 | output | Output of op-amp 2. Short-circuit protected; source ~40 mA / sink ~20 mA typical at VCC = 15 V. |
| 8 | OUT3 | output | Output of op-amp 3. Short-circuit protected to ground; class-AB output stage. |
| 9 | IN3- | input | Inverting input of op-amp 3. |
| 10 | IN3+ | input | Non-inverting input of op-amp 3. |
| 11 | VEE/GND | power_in | Negative supply rail. Tie to GND for single-supply operation (VCC up to 32 V), or to a negative rail down to -16 V for split supplies. |
| 12 | IN4+ | input | Non-inverting input of op-amp 4. |
| 13 | IN4- | input | Inverting input of op-amp 4. |
| 14 | OUT4 | output | Output of op-amp 4. Short-circuit protected; class-AB output stage. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 626 faces against 237 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.
