MC33274ADR2G from onsemi, in a SOIC-14. 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 | Amplifier 1 output. Class-AB NPN output stage; short-circuit current ±37 mA typ; output swing +13.9 V / −13.9 V into 2 kΩ at ±15 V supply. |
| 2 | IN1- | input | Amplifier 1 inverting input. Bipolar input, 300 nA typ bias current, 16 MΩ differential input resistance. ESD-protected via input diodes. |
| 3 | IN1+ | input | Amplifier 1 non-inverting input. Common-mode range extends from VEE to (VCC − 1.8 V). |
| 4 | VCC | power_in | Positive supply. +3.0 V to +36 V single-supply, or +1.5 V to +18 V in split-supply configuration. Total VCC-to-VEE must not exceed +36 V. |
| 5 | IN2+ | input | Amplifier 2 non-inverting input. Bipolar input; input voltage must not exceed VCC or VEE. |
| 6 | IN2- | input | Amplifier 2 inverting input. 300 nA typ bias current; 3.0 nA typ input offset current. |
| 7 | OUT2 | output | Amplifier 2 output. Unity-gain stable with capacitive loads up to 500 pF. |
| 8 | OUT3 | output | Amplifier 3 output. Class-AB NPN output stage with symmetrical source/sink; output swing +14.1 V / −14.6 V typical. |
| 9 | IN3- | input | Amplifier 3 inverting input. |
| 10 | IN3+ | input | Amplifier 3 non-inverting input. |
| 11 | VEE | power_in | Negative supply (or GND for single-supply operation). Tie to 0 V for single-supply use, or to negative rail (down to −18 V) for split-supply operation. |
| 12 | IN4+ | input | Amplifier 4 non-inverting input. |
| 13 | IN4- | input | Amplifier 4 inverting input. |
| 14 | OUT4 | output | Amplifier 4 output. Low open-loop output impedance (~35 Ω at 6 MHz). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 693 faces against 237 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.
