COS2374SR from COSINE, 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 | Amplifier A output. Rail-to-rail output; swings to within millivolts of each supply rail (typ. 1mV at RL=100kΩ, 8mV at 10kΩ, 40mV at 2kΩ). Short-circuit sourcing/sinking ~21/22 mA. |
| 2 | -IN1 | input | Inverting input of amplifier A. Input voltage range from -Vs -0.3V to +Vs +0.3V; input terminals are diode-clamped to the supply rails (limit external current to <=10 mA beyond the rails). |
| 3 | +IN1 | input | Non-inverting input of amplifier A. Rail-to-rail common-mode range (-0.1V to +5.6V at Vs=5.5V); same voltage-range limits as -IN1. |
| 4 | -Vs | power_in | Negative supply / ground. Tie to ground for single-supply operation (1.8V-5.5V on +Vs) or to a negative rail for dual-supply (±0.9V-±2.75V). If not grounded, bypass with a 0.1µF ceramic close to the pin. |
| 5 | +IN2 | input | Non-inverting input of amplifier B. Rail-to-rail common-mode range; same voltage-range limits as the other inputs. |
| 6 | -IN2 | input | Inverting input of amplifier B. Input voltage range from -Vs -0.3V to +Vs +0.3V; diode-clamped to the supply rails. |
| 7 | OUT2 | output | Amplifier B output. Rail-to-rail output, matching characteristics of OUT1. |
| 8 | +Vs | power_in | Positive supply, 1.8V to 5.5V (single supply) or +0.9V to +2.75V (dual). Absolute maximum +Vs to -Vs = 6.0V. Bypass with a 0.1µF ceramic capacitor placed as close as possible to this pin; a 2.2µF tantalum in parallel improves performance. |

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: 529 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.
