OPA348AIDR from UMW, in a SOP-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 | NC | unconnected | No internal connection. May be left floating or tied to any potential. |
| 2 | -In | input | Inverting input of the op-amp. CMOS gate; input bias current 0.5 pA typ. Common-mode range extends from (V-)-0.2 V to (V+)+0.2 V (rail-to-rail input). |
| 3 | +In | input | Non-inverting input of the op-amp. CMOS gate; input bias current 0.5 pA typ. Common-mode range extends from (V-)-0.2 V to (V+)+0.2 V (rail-to-rail input). |
| 4 | V- | power_in | Negative supply rail (or ground in single-supply operation). Total supply voltage V+ minus V- must be between 2.1 V and 5.5 V (7.5 V absolute max). |
| 5 | NC | unconnected | No internal connection. May be left floating or tied to any potential. |
| 6 | Out | output | Rail-to-rail amplifier output. Short-circuit current ±10 mA typ; drives to within 18 mV of the supply rails into 100 kΩ. |
| 7 | V+ | power_in | Positive supply rail. Single-supply operation 2.1 V to 5.5 V (7.5 V absolute max). Quiescent current 45 µA typ per amplifier. |
| 8 | NC | unconnected | No internal connection. May be left floating or tied to any potential. |

Two STEP files. Same geometry, different body top:

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 526 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.
