LF412CDR from Texas Instruments, in a SOIC-8-150mil. 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 | 1OUT | output | Amplifier 1 output. Max peak output voltage swing +/-13.5 V typ into 10 kOhm load at +/-15 V supplies. |
| 2 | 1IN- | input | Amplifier 1 inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current. |
| 3 | 1IN+ | input | Amplifier 1 non-inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current. |
| 4 | VCC- | power_in | Negative supply rail. Recommended -3.5 V to -18 V; absolute maximum -18 V. |
| 5 | 2IN+ | input | Amplifier 2 non-inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current. |
| 6 | 2IN- | input | Amplifier 2 inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current. |

3D model downloads
Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
lf412cdr.step |
122 KB | You want the bare part, or you mark your own boards. |
lf412cdr-etched.step |
1.5 MB | You want the part with LF412CDR already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 392 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.
