# COS9001TR

**COSINE** · Operational Amplifier · SOT23-5

COS9001TR 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 output voltage range extends to within millivolts of each supply rail. |
| 2 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass it with a 0.1µF capacitor as close to the part as possible. |
| 3 | +IN | input | Non-inverting input of the amplifier, with a voltage range of -Vs -0.3V to +Vs +0.3V. |
| 4 | -IN | input | Inverting input of the amplifier, with a voltage range of -Vs -0.3V to +Vs +0.3V. |
| 5 | +Vs | power_in | Positive power supply (1.8V to 7.0V); place a 0.1µF bypass capacitor as close to the part as possible. |
