COS8052SR 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. Rail-to-rail output stage; swing extends to within ~10 mV of each supply rail with light loads (RL=10kΩ) and within ~200 mV at RL=150Ω. Short-circuit sourcing ~100 mA, sinking ~120 mA. |
| 2 | -IN1 | input | Inverting input of amplifier A. Voltage range: -Vs - 0.3V to +Vs + 0.3V. Input terminals are diode-clamped to the supply rails; input signals swinging more than 0.5V beyond the rails must be current-limited to ≤10 mA. |
| 3 | +IN1 | input | Non-inverting input of amplifier A. Same voltage range as -IN1 (-Vs - 0.3V to +Vs + 0.3V). Common-mode voltage range spans -0.1V to +Vs + 0.1V (rail-to-rail input). |
| 4 | -Vs | power_in | Negative power supply or ground. For single-supply operation tie to ground; for dual-supply operation (±1.25V to ±2.25V) bypass to ground with a 0.1µF ceramic capacitor as close to the pin as possible. |
| 5 | +IN2 | input | Non-inverting input of amplifier B. Same voltage range as -IN2 (-Vs - 0.3V to +Vs + 0.3V). Rail-to-rail common-mode input range. |
| 6 | -IN2 | input | Inverting input of amplifier B. Voltage range: -Vs - 0.3V to +Vs + 0.3V. Diode-clamped to supply rails; limit fault current to ≤10 mA. |
| 7 | OUT2 | output | Output of amplifier B. Rail-to-rail output; swings within millivolts of each supply rail. Short-circuit current ~100 mA sourcing, ~120 mA sinking. |
| 8 | +Vs | power_in | Positive power supply. Operating range 2.5V to 5.5V single-supply (or +1.25V to +2.25V in dual-supply). Bypass with a 0.1µF ceramic capacitor as close to the pin as possible; a 2.2µF tantalum may be added for improved performance. Quiescent current per amplifier is 2.6 mA at Vs=5V. |
