Broadcom AVAGO · Operational Amplifier · DIP-8-300mil
QCPL-7847-500E from Broadcom AVAGO, in a DIP-8-300mil. 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 | VDD1 | power_in | Input-side supply voltage, 4.5 V to 5.5 V. Requires a 0.1 µF bypass capacitor between pins 1 and 4. |
| 2 | VIN+ | input | Non-inverting analog input of the isolation amplifier. Recommended linear input range ±200 mV (functional ±2 V); typically connected across a current-sense shunt resistor. |
| 3 | VIN- | input | Inverting analog input of the isolation amplifier. Recommended linear input range ±200 mV (functional ±2 V); typically tied to the low side of the current-sense shunt / GND1 in single-ended sensing. |
| 4 | GND1 | power_in | Input-side (isolated) ground reference for VDD1 and the analog inputs. |
| 5 | GND2 | power_in | Output-side ground reference for VDD2 and the differential outputs. |
| 6 | VOUT- | output | Inverting analog output of the isolated differential output pair. Differential (VOUT+ − VOUT-) is proportional to the input differential voltage across the isolation barrier. |
| 7 | VOUT+ | output | Non-inverting analog output of the isolated differential output pair. Typically converted to single-ended by an external op-amp per the recommended application circuit. |
| 8 | VDD2 | power_in | Output-side supply voltage, 4.5 V to 5.5 V. Requires a 0.1 µF bypass capacitor between pins 5 and 8. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 606 faces against 148 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.
