COSINE · Operational Amplifier · MSOP-8
COS2348MR 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 | OUT1 | output | Channel 1 (A) output, whose voltage range extends to within millivolts of each supply rail. |
| 2 | -IN1 | input | Channel 1 inverting input, with a voltage range from -Vs -0.3V to +Vs +0.3V. |
| 3 | +IN1 | input | Channel 1 non-inverting input, with the same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 4 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass it with a 0.1μF capacitor placed as close to the part as possible. |
| 5 | +IN2 | input | Channel 2 non-inverting input, with the same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 6 | -IN2 | input | Channel 2 inverting input, with a voltage range from -Vs -0.3V to +Vs +0.3V. |
| 7 | OUT2 | output | Channel 2 (B) output, whose voltage range extends to within millivolts of each supply rail. |
| 8 | +Vs | power_in | Positive power supply (1.8V to 5.5V), with a 0.1μF bypass capacitor placed as close to the part as possible. |
