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 (5.5 V absolute max). Requires a 0.1 uF bypass capacitor between pins 1 and 4. |+| 2 | VIN+ | input | Positive analog input to the isolation amplifier. Accurate/linear range -200 mV to +200 mV; functional range -2 V to +2 V (referenced to GND1). Typically connected across an external current-sense resistor. |+| 3 | VIN- | input | Negative analog input to the isolation amplifier. Accurate/linear range -200 mV to +200 mV; functional range -2 V to +2 V (referenced to GND1). Typically tied to the low side of the current-sense resistor. |+| 4 | GND1 | power_in | Input-side ground reference. Isolated from GND2 by the optical isolation barrier. |+| 5 | GND2 | power_in | Output-side ground reference. Isolated from GND1 by the optical isolation barrier. |+| 6 | VOUT- | output | Negative differential analog output, referenced to GND2. Combined with VOUT+ produces the isolated differential output proportional to the (VIN+ - VIN-) input. |+| 7 | VOUT+ | output | Positive differential analog output, referenced to GND2. Combined with VOUT- produces the isolated differential output proportional to the (VIN+ - VIN-) input. Absolute range -0.5 V to VDD2+0.5 V. |+| 8 | VDD2 | power_in | Output-side supply voltage, 4.5 V to 5.5 V (5.5 V absolute max). Requires a 0.1 uF bypass capacitor between pins 5 and 8. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Broadcom AVAGO |+| Package | DIP-8-300mil |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `QCPL-7847-000E`+- `QCPL-7847-000E300E`+- `QCPL-7847-000E500E`++## CAD (KiCad official)++- Symbol: `QCPL-7847-000E`+- Footprint: `Package_DIP:DIP-8_W7.62mm`+- 3D model: DIP-8-300mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Broadcom AVAGO datasheet](docs/qcpl-7847-000e-datasheet.pdf) (18 pp, sha256 `43bfeec4a87fb237`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
