MC33078D from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Output 1 | output | Output of amplifier 1; the output stage provides a large output voltage swing and symmetrical source and sink currents. |
| 2 | Inverting input 1 | input | Inverting input of amplifier 1. |
| 3 | Non-inverting input 1 | input | Non-inverting input of amplifier 1. |
| 4 | VCC- | power_in | Negative supply rail; the device operates from supplies of ±2.5 V to ±15 V (VCC+ to VCC- as a split supply). |
| 5 | Non-inverting input 2 | input | Non-inverting input of amplifier 2. |
| 6 | Inverting input 2 | input | Inverting input of amplifier 2. |
| 7 | Output 2 | output | Output of amplifier 2; the output stage provides a large output voltage swing and symmetrical source and sink currents. |
| 8 | VCC+ | power_in | Positive supply rail; the device operates from supplies of ±2.5 V to ±15 V, with absolute maximum supply voltage of ±18 V or +36 V. |
