QCPL-7847-500E

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.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
qcpl-7847-500e.step 271 KB You want the bare part, or you mark your own boards.
qcpl-7847-500e-etched.step 2.5 MB You want the part with QCPL-7847-500E already on it.

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
