OPA2348AIDCNR from Texas Instruments, in a SOT-23-8. 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 | OUTA | output | Channel A op-amp output. Rail-to-rail output stage; can swing to within ~25mV of either supply rail with a 100kΩ load. Short-circuit protected (typ ±10mA Isc). |
| 2 | -INA | input | Channel A inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Typical input bias current ±0.5pA. |
| 3 | +INA | input | Channel A non-inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Input signal current must be limited to 10mA if driven beyond the supply rails by more than 0.5V. |
| 4 | V- | power_in | Negative supply / ground rail. Total supply (V+ minus V-) must not exceed 7.5V absolute maximum; single-supply operation from 2.1V to 5.5V is typical, with V- tied to ground. |
| 5 | +INB | input | Channel B non-inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Input signal current must be limited to 10mA if driven beyond the supply rails by more than 0.5V. |
| 6 | -INB | input | Channel B inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Typical input bias current ±0.5pA. |
| 7 | OUTB | output | Channel B op-amp output. Rail-to-rail output stage; can swing to within ~25mV of either supply rail with a 100kΩ load. Short-circuit protected (typ ±10mA Isc). |
| 8 | V+ | power_in | Positive supply rail. Single-supply range 2.1V to 5.5V (specified 2.5V to 5.5V). Bypass to V- with a 0.1µF ceramic near the pin. Total quiescent current is typ 45µA/channel (90µA for dual). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 633 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.
