COSINE · Operational Amplifier · SOT23-5
COS9041TR from COSINE, in a SOT23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Amplifier output; the voltage range extends to within millivolts of each supply rail. |
| 2 | -Vs | power_in | Negative power supply or ground; bypass with a 0.1μF capacitor close to the part if not connected to ground. |
| 3 | +IN | input | Non-inverting input of the amplifier, with a voltage range from -Vs -0.3V to +Vs +0.3V. |
| 4 | -IN | input | Inverting input of the amplifier, with a voltage range from -Vs -0.3V to +Vs +0.3V. |
| 5 | +Vs | power_in | Positive power supply (1.8V to 7V); place a 0.1μF bypass capacitor as close to the part as possible. |
