SGM8270-2XMS8G from SGMICRO, in a MSOP-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 | Output of op-amp channel A. Rail-to-rail output with short-circuit protection; typical short-circuit current ±40mA at Vs=±18V. |
| 2 | -INA | input | Inverting input of op-amp channel A. High input impedance, rail-to-rail input; input common-mode range extends from (-Vs)-0.1V to (+Vs)+0.1V. |
| 3 | +INA | input | Non-inverting input of op-amp channel A. High input impedance, rail-to-rail input; input bias current typically ±10pA. |
| 4 | -Vs | power_in | Negative supply rail. Connect to ground for single-supply operation (3.3V to 36V) or to the negative supply for dual-supply operation (±1.65V to ±18V). |
| 5 | +INB | input | Non-inverting input of op-amp channel B. High input impedance, rail-to-rail input; input bias current typically ±10pA. |
| 6 | -INB | input | Inverting input of op-amp channel B. High input impedance, rail-to-rail input; input common-mode range extends from (-Vs)-0.1V to (+Vs)+0.1V. |
| 7 | OUTB | output | Output of op-amp channel B. Rail-to-rail output with short-circuit protection; typical short-circuit current ±40mA at Vs=±18V. |
| 8 | +Vs | power_in | Positive supply rail. Total supply voltage (+Vs to -Vs) is 3.3V to 36V (absolute max 40V). Quiescent current typically 1mA. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 739 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.
