COS8091SOT from COSINE, in a SOT23-5. 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 | OUT | output | Amplifier output. Output voltage swing extends to within millivolts of each supply rail (10 mV at RL=10 kΩ, 25 mV at RL=2 kΩ, 200 mV at RL=150 Ω). |
| 2 | -Vs | power_in | Negative power supply or ground. For single-supply operation tie to GND; for dual-supply operation bypass with a 0.1 µF ceramic capacitor placed as close to the pin as possible. |
| 3 | +IN | input | Non-inverting input of the amplifier. Common-mode voltage range is -Vs to +Vs (rail-to-rail); absolute input pin voltage range is -Vs -0.3 V to +Vs +0.3 V. |
| 4 | -IN | input | Inverting input of the amplifier. Voltage range at this pin is -Vs -0.3 V to +Vs +0.3 V; input bias current is typically ±3 pA. |
| 5 | +Vs | power_in | Positive power supply, 2.5 V to 5.5 V single-supply (or ±1.25 V to ±2.25 V dual-supply). Bypass with a 0.1 µF ceramic capacitor placed as close to the pin as possible. |
