LMV358B-VR

3PEAK · Operational Amplifier · MSOP-8

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).

CAD (KiCad official)

  • Symbol: LMV358B-VR
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: lmv358b-vr-etched.step / lmv358b-vr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmv358b-vr.step / lmv358b-vr.glb are the bare package body.

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.

Provenance
