Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Output of op-amp channel 1. Class-AB output stage; short-circuit current limited to ~40 mA. Do not short to VCC when VCC > 15 V (destructive dissipation possible). |
| 2 | IN1- | input | Inverting input of op-amp channel 1. Typical input bias current 20 nA, input offset current 2 nA. Do not drive below -0.3 V (input parasitic NPN action). |
| 3 | IN1+ | input | Non-inverting input of op-amp channel 1. Common-mode input range includes ground; upper limit is VCC - 1.5 V. |
| 4 | VCC+ | power_in | Positive supply rail. Single-supply operation 3 V to 30 V, or split-supply +1.5 V to +15 V. Absolute maximum ±16 V (single) or 32 V (single-supply). Total supply current typically 375 μA per amplifier. |
| 5 | IN2+ | input | Non-inverting input of op-amp channel 2. Common-mode input range includes ground. |
| 6 | IN2- | input | Inverting input of op-amp channel 2. Typical input bias current 20 nA. |
| 7 | OUT2 | output | Output of op-amp channel 2. Class-AB output stage; short-circuit current limited to ~40 mA. |
| 8 | OUT3 | output | Output of op-amp channel 3. Class-AB output stage; short-circuit current limited to ~40 mA. |
| 9 | IN3- | input | Inverting input of op-amp channel 3. Typical input bias current 20 nA. |
| 10 | IN3+ | input | Non-inverting input of op-amp channel 3. Common-mode input range includes ground. |
| 11 | VCC- | power_in | Negative supply rail / ground. Tie to GND for single-supply operation, or to negative rail (down to -15 V) for split-supply operation. |
| 12 | IN4+ | input | Non-inverting input of op-amp channel 4. Common-mode input range includes ground. |
| 13 | IN4- | input | Inverting input of op-amp channel 4. Typical input bias current 20 nA. |
| 14 | OUT4 | output | Output of op-amp channel 4. Class-AB output stage; short-circuit current limited to ~40 mA. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 452 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.
