LMV321LILT

STMicroelectronics · Operational Amplifier · SOT-23-5

LMV321LILT from STMicroelectronics, in a SOT-23-5. 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 In+ input Non-inverting input of the op-amp. Common-mode input range extends from (Vcc-)-0.2 V to (Vcc+)-1 V.
2 Vcc- power_in Negative supply / ground pin. Total supply voltage Vcc+ - Vcc- between 2.7 V and 5.5 V (6 V absolute maximum).
3 In- input Inverting input of the op-amp. Differential input voltage limited to +/-Vcc; input current must be limited to 10 mA by an external series resistor.
4 Out output Rail-to-rail op-amp output. Typical output swing 2.69 V high / 65 mV low into RL = 10 kOhm at Vcc = 2.7 V; slew rate 0.6 V/us.
5 Vcc+ power_in Positive supply pin. 2.7 V to 5.5 V operating range, 6 V absolute maximum. Typical supply current 120 uA per channel with no load.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lmv321lilt.step 85 KB You want the bare part, or you mark your own boards.
lmv321lilt-etched.step 1.3 MB You want the part with LMV321LILT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 354 faces against 102 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

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (21 pp, sha256 af991d0f244e0304, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
