MC33078D

STMicroelectronics · Operational Amplifier · SO-8

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.
