LMV614MTX from UMW, in a TSSOP-14. 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 | Op-amp A output. Rail-to-rail output; can swing within ~30 mV of rails with 2 kΩ load. Short-circuit sourcing/sinking ~8-9 mA. |
| 2 | INA- | input | Op-amp A inverting input. IB ~15 nA typ; input voltage must remain within V-−0.3 V to V++0.3 V. |
| 3 | INA+ | input | Op-amp A non-inverting input. Common-mode range extends 200 mV beyond both supply rails. |
| 4 | V+ | power_in | Positive supply input. Operating range 1.8 V to 5.5 V (absolute max V+−V- = 6 V). Total supply current ~103 µA/channel typ (185 µA max). |
| 5 | INB+ | input | Op-amp B non-inverting input. Rail-to-rail input common-mode range. |
| 6 | INB- | input | Op-amp B inverting input. |
| 7 | OUTB | output | Op-amp B output. Rail-to-rail output driver. |
| 8 | OUTC | output | Op-amp C output. Rail-to-rail output driver. |
| 9 | INC- | input | Op-amp C inverting input. |
| 10 | INC+ | input | Op-amp C non-inverting input. |
| 11 | V- | power_in | Negative supply input (typically GND in single-supply operation). Absolute max V+−V- = 6 V. |
| 12 | IND+ | input | Op-amp D non-inverting input. |
| 13 | IND- | input | Op-amp D inverting input. |
| 14 | OUTD | output | Op-amp D output. Rail-to-rail output driver. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
lmv614mtx.step |
194 KB | You want the bare part, or you mark your own boards. |

1.7 MB | You want the part with LMV614MTX already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 456 faces against 237 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.
