LMV358B-SR from 3PEAK, 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	OUTA	output	Amplifier A output. Rail-to-rail output stage capable of sourcing/sinking up to ~100 mA short-circuit current; typical output swing to within 15 mV of the rails with R_LOAD = 10 kΩ.
2	-INA	input	Amplifier A inverting input. Rail-to-rail CMOS input; input bias current ~1 pA at 25°C. Common-mode range extends 100 mV beyond each supply rail.
3	+INA	input	Amplifier A non-inverting input. Rail-to-rail CMOS input; input offset voltage +1 mV typ, +4 mV max. Input protection diodes to each supply rail; limit input current beyond rails to <10 mA.
4	-VS	power_in	Negative supply / ground. Connect to 0 V for single-supply operation, or to the negative rail for split-supply operation. Total (+VS) − (−VS) must not exceed 6 V absolute max (2.5 V to 5.5 V operating).
5	+INB	input	Amplifier B non-inverting input. Rail-to-rail CMOS input; ~1 pA typical input bias current.
6	-INB	input	Amplifier B inverting input. Rail-to-rail CMOS input matched to +INB; differential input voltage limited to ±6 V absolute max.
7	OUTB	output	Amplifier B output. Rail-to-rail output; short-circuit protected (infinite duration per abs-max notes, with adequate thermal sinking).
8	+VS	power_in	Positive supply. 2.5 V to 5.5 V operating (6 V absolute max across supplies). Quiescent current 80 µA per amplifier (160 µA total typical). Decouple locally with a 0.1 µF ceramic capacitor to −VS.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv358b-sr.step`	122 KB	You want the bare part, or you mark your own boards.
`lmv358b-sr-etched.step`	2.2 MB	You want the part with `LMV358B-SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 544 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.
