COS2172SRA 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 swing extends to within ~500mV of each supply rail (RRIO) with sourcing capability of +40mA and sinking of -48mA short-circuit current. |
| 2 | -IN1 | input | Inverting input of amplifier A. Voltage range of this pin can go from -Vs -0.3V to +Vs + 0.3V. Input terminals are diode-clamped to the power-supply rails; limit current to ±10mA if signal exceeds the rails by 0.5V. |
| 3 | +IN1 | input | Non-inverting input of amplifier A. Same voltage range as -IN1 (-Vs -0.3V to +Vs +0.3V). Rail-to-rail input; common-mode range spans V-S -0.1V to V+S -2V per the electrical characteristics. |
| 4 | -Vs | power_in | Negative power supply or ground. For single-supply operation tie to GND; for dual-supply operation tie to the negative rail (down to -20V). Bypass with a 0.1µF ceramic capacitor placed close to the pin if not connected directly to ground. |
| 5 | +IN2 | input | Non-inverting input of amplifier B. Same voltage range as -IN2 (-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. Input terminals are diode-clamped to the supply rails. |
| 7 | OUT2 | output | Output of amplifier B. Rail-to-rail output that swings to within ~500mV of each supply rail with a 10kΩ load at Vs=40V. |
| 8 | +Vs | power_in | Positive power supply, 4.5V to 40V single-supply (or up to +20V in dual-supply operation). Quiescent current is 1.2mA per amplifier. Bypass with a 0.1µF ceramic capacitor placed as close to the pin as possible; a 2.2µF tantalum capacitor may be added for better performance. |
