COS2171SRA
COSINE · Operational Amplifier · SOP-8
COS2171SRA from COSINE, in a SOP-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 amplifier A. Output voltage range extends to within ~500mV of each supply rail (RRIO). |
| 2 | -IN1 | input | Inverting input of amplifier A. Voltage range from -Vs - 0.3V to +Vs + 0.3V; inputs are diode-clamped to the supply rails. |
| 3 | +IN1 | input | Non-inverting input of amplifier A. Voltage range from -Vs - 0.3V to +Vs + 0.3V; rail-to-rail input capability. |
| 4 | -Vs | power_in | Negative power supply or ground. For dual-supply operation ±2.25V to ±20V; bypass with 0.1µF ceramic as close to the pin as possible. |
| 5 | +IN2 | input | Non-inverting input of amplifier B. Voltage range from -Vs - 0.3V to +Vs + 0.3V; rail-to-rail input capability. |
| 6 | -IN2 | input | Inverting input of amplifier B. Voltage range from -Vs - 0.3V to +Vs + 0.3V; inputs are diode-clamped to the supply rails. |
| 7 | OUT2 | output | Output of amplifier B. Output voltage range extends to within ~500mV of each supply rail (RRIO). |
| 8 | +Vs | power_in | Positive power supply, 4.5V to 40V (single-supply) or +2.25V to +20V (dual-supply). Bypass with 0.1µF ceramic capacitor as close to the pin as possible; a 2.2µF tantalum can be added for better performance. |

Two STEP files. Same geometry, different body top:

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 512 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.
