COS6004SR from COSINE, in a SOIC-14. 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	OUTA	output	Output of amplifier A. Rail-to-rail output; swing extends to within millivolts of each supply rail (typ. 1mV with RL=100k, 8mV with RL=10k, 40mV with RL=2k).
2	-INA	input	Inverting input of amplifier A. Input voltage range from -Vs - 0.3V to +Vs + 0.3V; input terminals are diode-clamped to the supply rails.
3	+INA	input	Non-inverting input of amplifier A. Rail-to-rail input; same voltage range as -IN.
4	+Vs	power_in	Positive power supply, 1.8V to 5.5V (single-supply) or +0.9V to +2.75V (dual-supply). Bypass with a 0.1uF ceramic capacitor placed close to this pin; 2.2uF tantalum can be added for improved performance.
5	+INB	input	Non-inverting input of amplifier B. Rail-to-rail input; same voltage range as -IN.
6	-INB	input	Inverting input of amplifier B. Input voltage range from -Vs - 0.3V to +Vs + 0.3V.
7	OUTB	output	Output of amplifier B. Rail-to-rail output. Short-circuit current typ. 21mA sourcing / 22mA sinking.
8	OUTC	output	Output of amplifier C. Rail-to-rail output.
9	-INC	input	Inverting input of amplifier C. Input voltage range from -Vs - 0.3V to +Vs + 0.3V.
10	+INC	input	Non-inverting input of amplifier C. Rail-to-rail input.
11	-Vs	power_in	Negative power supply or ground. If not connected to ground, bypass with a 0.1uF capacitor placed close to this pin. For dual-supply operation: -0.9V to -2.75V.
12	+IND	input	Non-inverting input of amplifier D. Rail-to-rail input.
13	-IND	input	Inverting input of amplifier D. Input voltage range from -Vs - 0.3V to +Vs + 0.3V.
14	OUTD	output	Output of amplifier D. Rail-to-rail output.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cos6004sr.step`	195 KB	You want the bare part, or you mark your own boards.
`cos6004sr-etched.step`	2.7 MB	You want the part with `COS6004SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 648 faces against 237 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.
