LMV358MR 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	OUTA	output	Output of amplifier A. Rail-to-rail output; swings to within ~10 mV of each supply rail with a 10 kΩ load.
2	-IN1	input	Inverting input of amplifier A. Common-mode input range: -Vs - 0.3 V to +Vs - 1 V. Input terminals are diode-clamped to the supply rails.
3	+IN1	input	Non-inverting input of amplifier A. Same input voltage range as -IN1.
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 µF ceramic capacitor placed close to the pin. Total supply (+Vs to -Vs) range 2.1 V to 5.5 V.
5	+IN2	input	Non-inverting input of amplifier B. Same input voltage range as -IN2.
6	-IN2	input	Inverting input of amplifier B. Common-mode input range: -Vs - 0.3 V to +Vs - 1 V. Input terminals are diode-clamped to the supply rails.
7	OUTB	output	Output of amplifier B. Rail-to-rail output; swings to within ~10 mV of each supply rail with a 10 kΩ load.
8	+Vs	power_in	Positive power supply, 2.1 V to 5.5 V (single-supply) or +1.05 V to +2.75 V (dual-supply). Bypass with a 0.1 µF ceramic capacitor placed as close to the pin as possible; a 2.2 µF tantalum may be added for better performance.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv358mr.step`	123 KB	You want the bare part, or you mark your own boards.
`lmv358mr-etched.step`	1.8 MB	You want the part with `LMV358MR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 448 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.
