CC6937S8-3FB010 from Cross chip, in a SOP-8. 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 | Positive current path terminal accepting Hall effect measurement input with ±10A range. |
| 2 | IP+ | passive | Positive current path terminal accepting Hall effect measurement input with ±10A range. |
| 3 | IP- | passive | Negative current path terminal for Hall effect measurement with ±10A range. |
| 4 | IP- | passive | Negative current path terminal for Hall effect measurement with ±10A range. |
| 5 | GND | power_in | Ground reference with 3750V RMS isolation from primary current path (pins 1-4). |
| 6 | VREF | power_in | Reference voltage output nominally 1.65V (1.60-1.70V range at 3.3V VCC) or external input 0-4V for output midpoint adjustment. |
| 7 | VOUT | output | Measurement output voltage nominally 1.65V at zero current with 132 mV/A sensitivity for ±10A input range. |
| 8 | VCC | power_in | Supply voltage input nominally 3.3V with operating range 3.0-3.6V and typical quiescent current 9mA. |
