LMV324 from TECH PUBLIC, in a SOP-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 | Output of amplifier A. Rail-to-rail output; can typically swing within 10mV of the supply rails with light loads (>100kΩ). |
| 2 | INA- | input | Inverting input of amplifier A. Rail-to-rail input; common-mode range extends 100mV beyond the supply rails (Vss-0.1V to VDD+0.1V). Input bias current typ. 10pA. |
| 3 | INA+ | input | Non-inverting input of amplifier A. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |
| 4 | VDD | power_in | Positive supply. Single-supply operation 2.2V to 5.5V (absolute max 7V). Bypass to VSS with a 0.1µF ceramic capacitor placed close to the pin. |
| 5 | INB+ | input | Non-inverting input of amplifier B. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |
| 6 | INB- | input | Inverting input of amplifier B. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |
| 7 | OUTB | output | Output of amplifier B. Rail-to-rail output; short-circuit current typ. ±20mA. |
| 8 | OUTC | output | Output of amplifier C. Rail-to-rail output; short-circuit current typ. ±20mA. |
| 9 | INC- | input | Inverting input of amplifier C. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |
| 10 | INC+ | input | Non-inverting input of amplifier C. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |
| 11 | VSS | power_in | Negative supply / ground. Tie to 0V in single-supply operation, or -1.1V to -2.75V in dual-supply operation. Bypass with 0.1µF ceramic capacitor if used as a supply. |
| 12 | IND+ | input | Non-inverting input of amplifier D. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |
| 13 | IND- | input | Inverting input of amplifier D. Rail-to-rail input; common-mode range Vss-0.1V to VDD+0.1V. |
| 14 | OUTD | output | Output of amplifier D. Rail-to-rail output; short-circuit current typ. ±20mA. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
lmv324.step |
195 KB | You want the bare part, or you mark your own boards. |
lmv324-etched.step |
1.6 MB | You want the part with LMV324 already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 408 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.
