COS8554SR from COSINE, in a SOP-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 | Amplifier 1 output. Rail-to-rail; swings to within ~5mV of each supply rail (RL=100kΩ) or ~15mV (RL=10kΩ). |
| 2 | -IN1 | input | Amplifier 1 inverting input. Input voltage range -Vs-0.3V to +Vs+0.3V; diode-clamped to supply rails. |
| 3 | +IN1 | input | Amplifier 1 non-inverting input. Same voltage range as -IN1. |
| 4 | +Vs | power_in | Positive supply rail, 1.8V to 5.5V. Bypass with a 0.1µF capacitor placed as close to the part as possible, between +Vs and -Vs (or +Vs and ground). |
| 5 | +IN2 | input | Amplifier 2 non-inverting input. |
| 6 | -IN2 | input | Amplifier 2 inverting input. |
| 7 | OUT2 | output | Amplifier 2 output. |
| 8 | OUT3 | output | Amplifier 3 output. |
| 9 | -IN3 | input | Amplifier 3 inverting input. |
| 10 | +IN3 | input | Amplifier 3 non-inverting input. |
| 11 | -Vs | power_in | Negative supply or ground. If not tied to ground, bypass with a 0.1µF capacitor as close to the part as possible. |
| 12 | +IN4 | input | Amplifier 4 non-inverting input. |
| 13 | -IN4 | input | Amplifier 4 inverting input. |
| 14 | OUT4 | output | Amplifier 4 output. |

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

195 KB | You want the bare part, or you mark your own boards. |

2.7 MB | You want the part with COS8554SR already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 647 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.
