MC33078MDREP from Texas Instruments, in a SOIC-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 | OUT1 | output | Output of amplifier 1, which may be shorted to ground or either power supply for an unlimited duration. |
| 2 | IN1− | input | Inverting input of amplifier 1; the input voltage magnitude must never exceed the supply voltage magnitude, and differential input above approximately 0.6 V draws excessive current unless a limiting resistor is used. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1; the input voltage magnitude must never exceed the supply voltage magnitude, and differential input above approximately 0.6 V draws excessive current unless a limiting resistor is used. |
| 4 | VCC− | power_in | Negative supply, recommended range −5 V to −18 V with an absolute maximum of −18 V. |
| 5 | IN2+ | input | Non-inverting input of amplifier 2; the input voltage magnitude must never exceed the supply voltage magnitude, and differential input above approximately 0.6 V draws excessive current unless a limiting resistor is used. |
| 6 | IN2− | input | Inverting input of amplifier 2; the input voltage magnitude must never exceed the supply voltage magnitude, and differential input above approximately 0.6 V draws excessive current unless a limiting resistor is used. |
| 7 | OUT2 | output | Output of amplifier 2, which may be shorted to ground or either power supply for an unlimited duration. |
| 8 | VCC+ | power_in | Positive supply, recommended range 5 V to 18 V with an absolute maximum of 18 V. |
