COS6004TR from COSINE, in a TSSOP-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	Amplifier A output. Rail-to-rail output that swings to within millivolts of each supply rail.
2	-INA	input	Amplifier A inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
3	+INA	input	Amplifier A non-inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
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 0.1µF ceramic capacitor placed close to the pin.
5	+INB	input	Amplifier B non-inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
6	-INB	input	Amplifier B inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
7	OUTB	output	Amplifier B output. Rail-to-rail output that swings to within millivolts of each supply rail.
8	OUTC	output	Amplifier C output. Rail-to-rail output that swings to within millivolts of each supply rail.
9	-INC	input	Amplifier C inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
10	+INC	input	Amplifier C non-inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
11	-Vs	power_in	Negative power supply or ground. If not tied to ground, bypass with a 0.1µF ceramic capacitor as close to the pin as possible.
12	+IND	input	Amplifier D non-inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
13	-IND	input	Amplifier D inverting input. Voltage range from -Vs -0.3V to +Vs + 0.3V.
14	OUTD	output	Amplifier D output. Rail-to-rail output that swings to within millivolts of each supply rail.

CAD (KiCad official)

3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cos6004tr.step`	194 KB	You want the bare part, or you mark your own boards.
`cos6004tr-etched.step`	2.5 MB	You want the part with `COS6004TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 608 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.
