COS6002SR from COSINE, in a SOIC-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	Amplifier A output. Rail-to-rail output; voltage swing extends to within millivolts of each supply rail (typ 1 mV at RL=100 kOhm, 40 mV at RL=2 kOhm). Short-circuit current ~21 mA sourcing / 22 mA sinking.
2	-IN1	input	Inverting input of amplifier A. Voltage range from -Vs -0.3V to +Vs +0.3V. Input bias current ~2.5 pA; internally diode-clamped to the supply rails (limit input current to <= 10 mA).
3	+IN1	input	Non-inverting input of amplifier A. Same voltage range as -IN1 (-Vs -0.3V to +Vs +0.3V). Rail-to-rail input common-mode range.
4	-Vs	power_in	Negative power supply or ground. For single-supply operation tie to GND; for dual-supply operation, bypass to ground with a 0.1 uF ceramic close to the pin. Total supply (+Vs to -Vs) 1.8 V to 5.5 V, absolute max 6.0 V.
5	+IN2	input	Non-inverting input of amplifier B. Rail-to-rail input; voltage range -Vs -0.3V to +Vs +0.3V.
6	-IN2	input	Inverting input of amplifier B. Voltage range from -Vs -0.3V to +Vs +0.3V. Input bias current ~2.5 pA; internally diode-clamped to the supply rails.
7	OUT2	output	Amplifier B output. Rail-to-rail output swinging to within millivolts of each supply rail.
8	+Vs	power_in	Positive power supply. Operating range 1.8 V to 5.5 V (absolute max 6.0 V from +Vs to -Vs). Bypass with a 0.1 uF ceramic capacitor placed as close to the pin as possible; a 2.2 uF tantalum may be added for improved performance. Quiescent current ~50 uA per amplifier.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cos6002sr.step`	122 KB	You want the bare part, or you mark your own boards.
`cos6002sr-etched.step`	2.5 MB	You want the part with `COS6002SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 583 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
