OPA2348AIDR from Texas Instruments, in a SOIC-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 | Out A | output | Channel A op-amp output. Rail-to-rail output, ±10 mA short-circuit current, drives loads down to 5 kΩ over the full output swing. |
| 2 | -In A | input | Channel A inverting input. CMOS gate input with 0.5pA typical bias current; input common-mode range extends from (V-)-0.2V to (V+)+0.2V. |
| 3 | +In A | input | Channel A non-inverting input. CMOS gate input with 0.5pA typical bias current; rail-to-rail common-mode range. |
| 4 | V- | power_in | Negative supply rail (or ground for single-supply operation). Supply span V+ to V- is 2.1V to 5.5V (7.5V absolute max). |
| 5 | +In B | input | Channel B non-inverting input. CMOS gate input with 0.5pA typical bias current; rail-to-rail common-mode range. |
| 6 | -In B | input | Channel B inverting input. CMOS gate input with 0.5pA typical bias current. |
| 7 | Out B | output | Channel B op-amp output. Rail-to-rail output, ±10 mA short-circuit current. |
| 8 | V+ | power_in | Positive supply rail. 2.1V to 5.5V single-supply operation; 7.5V absolute maximum between V+ and V-. Quiescent current 45µA/amp typical. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 571 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.
