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 | IP+ | passive | Primary current input (positive terminal). Internally tied to pin 2 through the low-resistance (0.9 mΩ typ) integrated copper conductor. Current flows from IP+ (pins 1-2) to IP- (pins 3-4) for a positive reading. Isolated from the signal side by 3500 Vrms. |+| 2 | IP+ | passive | Primary current input (positive terminal), second lead of the IP+ side of the integrated copper conductor. Must be paralleled with pin 1 on the PCB. |+| 3 | IP- | passive | Primary current output (negative terminal), first lead of the IP- side of the integrated copper conductor. Must be paralleled with pin 4 on the PCB. |+| 4 | IP- | passive | Primary current output (negative terminal), second lead of the IP- side of the integrated copper conductor. Must be paralleled with pin 3 on the PCB. |+| 5 | GND | power_in | Signal-side ground reference for VCC, VOUT, and VZCR. Isolated from the primary current path (IP+/IP-) by 3500 Vrms (basic isolation 424 Vrms). |+| 6 | VZCR | output | Zero-current reference signal output (typically VCC/2). Source current up to 400 µA, sink current up to 3 mA; recommended design margin keeps IZCR < 0.4 mA (reserve ~0.3 mA). Used as a stable reference for downstream difference amplifiers. |+| 7 | OUT | output | Analog voltage output proportional to primary current. For the 5A variant: VOUT = VCC/2 + 0.400 × IP(A). Zero-current output = VCC/2 (2.490-2.510 V at VCC=5V). Linear range 0.5-4.5 V, source current 6 mA / sink 30 mA max, drives up to 1 nF load with ≥1.5 kΩ pull. |+| 8 | VCC | power_in | Analog supply, 4.5-5.5 V (5 V typ), 20 mA typ / 25 mA max quiescent. Absolute maximum 7 V. Decouple with a 0.1 µF ceramic to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Cross chip |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `CC6920SO-5ACC6920SO-2.5A`+- `CC6920SO-5A`+- `CC6920SO-5ACC6920SO-10A`+- `CC6920SO-5ACC6920SO-20A`+- `CC6920SO-5ACC6920SO-25A`+- `CC6920SO-5ACC6920SO-30A`+- `CC6920SO-5ACC6920SO-40A`+- `CC6920SO-5ACC6920SO-50A`+- `CC6920SO-5ACC6920SO-XXA`++## CAD (KiCad official)++- Symbol: `CC6920SO-5A`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Cross chip datasheet](docs/cc6920so-5a-datasheet.pdf) (23 pp, sha256 `5fe4aa3fee763407`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
