COSINE · Precision Op Amps · MSOP-8
COS1177MR from COSINE, in a MSOP-8. 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 | NC | unconnected | No connection. |
| 2 | -IN | input | Inverting input of the amplifier; voltage range can go from -Vs to +Vs. |
| 3 | +IN | input | Non-inverting input of the amplifier; same voltage range as -IN (-Vs to +Vs). |
| 4 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass with a 0.1µF capacitor placed as close to the part as possible. |
| 5 | NC | unconnected | No connection. |
| 6 | OUT | output | Amplifier output; the output voltage range extends to within millivolts of each supply rail. |
| 7 | +Vs | power_in | Positive power supply; place a 0.1µF bypass capacitor as close to the part as possible between the supply pins or between the supply pins and ground. |
| 8 | NC | unconnected | No connection. |
