OPA2340EA from Texas Instruments, in a VSSOP-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 | Output of channel A op-amp. Rail-to-rail output stage swings to within 1 mV of the supply rails with a 100-kΩ load. |
| 2 | -IN A | input | Negative (inverting) input of channel A. Rail-to-rail input common-mode range extends 500 mV beyond each supply rail. |
| 3 | +IN A | input | Positive (noninverting) input of channel A. Rail-to-rail input common-mode range extends 500 mV beyond each supply rail. |
| 4 | V- | power_in | Negative (lowest) power supply. Single-supply operation ties this pin to ground; total supply (V+ - V-) is 2.7 V to 5.5 V. |
| 5 | +IN B | input | Positive (noninverting) input of channel B. Rail-to-rail input common-mode range extends 500 mV beyond each supply rail. |
| 6 | -IN B | input | Negative (inverting) input of channel B. Rail-to-rail input common-mode range extends 500 mV beyond each supply rail. |
| 7 | OUT B | output | Output of channel B op-amp. Rail-to-rail output stage swings to within 1 mV of the supply rails with a 100-kΩ load. |
| 8 | V+ | power_in | Positive (highest) power supply, 2.7 V to 5.5 V single-supply or split-supply operation. Bypass to V- with 0.1 μF ceramic capacitor. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 475 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.
