LM2904AVQDR 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 | OUT1 | output | Output of op-amp channel 1. Class-AB output stage capable of sinking/sourcing loads to V- (ground in single-supply operation). Short-circuit to V- allowed indefinitely for VS ≤ 15 V at TA = 25 °C. |
| 2 | IN1- | input | Inverting (negative) input of op-amp channel 1. High-impedance BJT input; differential input voltage rated ±32 V (VID). Input voltage range -0.3 V to 32 V. |
| 3 | IN1+ | input | Non-inverting (positive) input of op-amp channel 1. Common-mode input range includes V- (ground), enabling ground sensing in single-supply operation. |
| 4 | V- | power_in | Negative (lowest) supply rail, or ground for single-supply operation. Supply span (V+) - (V-) rated up to 32 V for the AV/A variants (26 V absolute max on plain LM2904). |
| 5 | IN2+ | input | Non-inverting (positive) input of op-amp channel 2. Common-mode input range includes V- (ground). |
| 6 | IN2- | input | Inverting (negative) input of op-amp channel 2. High-impedance BJT input; differential input voltage rated ±32 V. |
| 7 | OUT2 | output | Output of op-amp channel 2. Class-AB output stage capable of sinking/sourcing loads to V- (ground in single-supply operation). |
| 8 | V+ | power_in | Positive (highest) supply rail. Recommended supply range 3 V to 32 V (LM2904AV); absolute-maximum total supply is 32 V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 532 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.
