## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Positive sampling-current terminal of the internal primary conductor; the recommended DC current range is -30 to 30 A and the transient is 100 A for one 100 ms pulse (absolute maximum). |
| 2 | IP+ | passive | Second positive sampling-current terminal, bonded to pin 1; the recommended DC current range is -30 to 30 A and the transient is 100 A for one 100 ms pulse (absolute maximum). |
| 3 | IP- | passive | Negative sampling-current terminal of the internal primary conductor; the recommended DC current range is -30 to 30 A and the transient is 100 A for one 100 ms pulse (absolute maximum). |
| 4 | IP- | passive | Second negative sampling-current terminal, bonded to pin 3; the recommended DC current range is -30 to 30 A and the transient is 100 A for one 100 ms pulse (absolute maximum). |
| 5 | GND | power_in | Ground reference pin for the device. |
| 6 | NC | unconnected | No connection; the datasheet requires this pin to be left floating (需悬空). |
| 7 | OUT | output | Single-ended analog voltage output; the absolute maximum output source current is 400 µA, sink current is 30 mA, and output voltage is limited to -0.3 V to VCC+0.3 V. |
| 8 | VCC | power_in | Supply voltage pin; the recommended supply range is 3.0 to 3.6 V and the absolute maximum is 7 V. |
