LMV358B-VR from 3PEAK, 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, capable of sourcing/sinking up to ~100mA short-circuit current.
2	-INA	input	Inverting input of amplifier A. Rail-to-rail input; common-mode range extends 100mV beyond V- and V+.
3	+INA	input	Non-inverting input of amplifier A. Rail-to-rail input; input bias current ~1pA at 25°C.
4	-Vs	power_in	Negative supply / ground. Typically 0V in single-supply operation; supply range (V+)-(V-) = 2.5V to 5.5V.
5	+INB	input	Non-inverting input of amplifier B. Rail-to-rail input; input bias current ~1pA at 25°C.
6	-INB	input	Inverting input of amplifier B. Rail-to-rail input; common-mode range extends 100mV beyond V- and V+.
7	OUTB	output	Output of amplifier B. Rail-to-rail output, capable of sourcing/sinking up to ~100mA short-circuit current.
8	+Vs	power_in	Positive supply. 2.5V to 5.5V single-supply; absolute maximum 6V. Quiescent current 80µA/amplifier (160µA total typ).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv358b-vr.step`	123 KB	You want the bare part, or you mark your own boards.
`lmv358b-vr-etched.step`	2.0 MB	You want the part with `LMV358B-VR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 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.
