COS4177SR from COSINE, in a SOP-14. 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 | OUTA | output | Output of amplifier A, which swings to within millivolts of each supply rail. |
| 2 | -INA | input | Inverting input of amplifier A, voltage range from -Vs to +Vs. |
| 3 | +INA | input | Non-inverting input of amplifier A, same voltage range as the inverting input (-Vs to +Vs). |
| 4 | +Vs | power_in | Positive power supply (+2.5V to +18V with dual supplies, 36V total max); bypass with 0.1µF close to the pin. |
| 5 | +INB | input | Non-inverting input of amplifier B, same voltage range as the inverting input (-Vs to +Vs). |
| 6 | -INB | input | Inverting input of amplifier B, voltage range from -Vs to +Vs. |
| 7 | OUTB | output | Output of amplifier B, which swings to within millivolts of each supply rail. |
| 8 | OUTC | output | Output of amplifier C, which swings to within millivolts of each supply rail. |
| 9 | -INC | input | Inverting input of amplifier C, voltage range from -Vs to +Vs. |
| 10 | +INC | input | Non-inverting input of amplifier C, same voltage range as the inverting input (-Vs to +Vs). |
| 11 | -Vs | power_in | Negative power supply or ground; bypass with 0.1µF close to the pin if not grounded. |
| 12 | +IND | input | Non-inverting input of amplifier D, same voltage range as the inverting input (-Vs to +Vs). |
| 13 | -IND | input | Inverting input of amplifier D, voltage range from -Vs to +Vs. |
| 14 | OUTD | output | Output of amplifier D, which swings to within millivolts of each supply rail. |
