# COS6002MR

**COSINE** · Operational Amplifier · MSOP-8

COS6002MR from COSINE, in a MSOP-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; voltage swing extends to within ~1mV (100kΩ load) to ~40mV (2kΩ load) of each supply rail. Short-circuit sourcing 21mA / sinking 22mA typical. |
| 2 | -IN1 | input | Inverting input of amplifier A. Rail-to-rail input; voltage range from -Vs-0.3V to +Vs+0.3V (absolute max -Vs-0.5V to +Vs+0.5V). Input bias current ±2.5pA typical. |
| 3 | +IN1 | input | Non-inverting input of amplifier A. Same voltage range as -IN1 (rail-to-rail input, -Vs-0.3V to +Vs+0.3V). |
| 4 | -Vs | power_in | Negative power supply or ground. For single-supply operation connect to GND; for dual-supply connect to negative rail (down to -2.75V). If not tied to GND, bypass with 0.1µF ceramic close to the pin. |
| 5 | +IN2 | input | Non-inverting input of amplifier B. Rail-to-rail input; voltage range from -Vs-0.3V to +Vs+0.3V. |
| 6 | -IN2 | input | Inverting input of amplifier B. Rail-to-rail input; voltage range from -Vs-0.3V to +Vs+0.3V. Input bias current ±2.5pA typical. |
| 7 | OUT2 | output | Output of amplifier B. Rail-to-rail output; voltage swing extends to within ~1mV (100kΩ load) to ~40mV (2kΩ load) of each supply rail. |
| 8 | +Vs | power_in | Positive power supply. Operating range 1.8V to 5.5V single-supply (or +0.9V to +2.75V dual-supply). Absolute max 6.0V. Bypass with 0.1µF ceramic close to the pin; a 2.2µF tantalum in parallel improves performance. |
