CC6905S8-5FB040 from Cross chip, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Current-sampled positive terminal of the primary copper conductor, with 100 VRMS isolation between pins 1-4 and pins 5-8. |
| 2 | IP+ | passive | Second current-sampled positive terminal (IP+), listed with the same function as pin 1. |
| 3 | IP- | passive | Current-sampled negative terminal of the primary copper conductor, with 100 VRMS isolation from pins 5-8. |
| 4 | IP- | passive | Second current-sampled negative terminal (IP-), listed with the same function as pin 3. |
| 5 | GND | power_in | Ground reference pin for the sensor circuit. |
| 6 | VREF | power_in | Built-in reference output voltage, used to set the quiescent output level; the datasheet also offers an external VREF input option. |
| 7 | VOUT | output | Single-ended analog output voltage, with an absolute maximum of VCC + 0.3 V and a maximum output source current of 25 mA. |
| 8 | VCC | power_in | Supply voltage input, with an absolute maximum rating of 6.5 V. |
