LM2904AMM from HGSEMI, 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 | 1OUT | output | Output of op-amp channel 1. Can source ~40 mA and sink ~20 mA at V+=15V; output voltage swing reaches near VEE and up to (V+ - 1.5V). |
| 2 | 1IN- | input | Inverting input of op-amp channel 1. Input bias current typ. 45 nA. Common-mode range 0 V to (V+ - 1.5V). |
| 3 | 1IN+ | input | Non-inverting input of op-amp channel 1. Input bias current typ. 45 nA. Common-mode range extends to the negative supply (ground in single-supply operation). |
| 4 | VEE | power_in | Negative supply / ground pin. Tie to GND for single-supply operation, or to V- for split-supply operation. Absolute max supply span 32V (or ±16V). |
| 5 | 2IN+ | input | Non-inverting input of op-amp channel 2. Input bias current typ. 45 nA. Common-mode range extends to the negative supply. |
| 6 | 2IN- | input | Inverting input of op-amp channel 2. Input bias current typ. 45 nA. Common-mode range 0 V to (V+ - 1.5V). |
| 7 | 2OUT | output | Output of op-amp channel 2. Can source ~40 mA and sink ~20 mA at V+=15V; short-circuit current ~40-60 mA at V+=15V, Ta=25°C. |
| 8 | VCC | power_in | Positive supply pin. Accepts 3V to 32V (single supply) or ±1.5V to ±16V (split supply). Supply current typ. 1 mA at V+=30V; 0.5 mA at V+=5V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 445 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.
