Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Positive terminal of the input current path (pins 1 and 2 tied), part of the ~1.0 mΩ typical conductor that is isolated at 2.5 kVrms 1 min from signal pins 5-8. |
| 2 | IP+ | passive | Positive terminal of the input current path (pins 1 and 2 tied), part of the ~1.0 mΩ typical conductor that is isolated at 2.5 kVrms 1 min from signal pins 5-8. |
| 3 | IP- | passive | Negative terminal of the input current path (pins 3 and 4 tied); current flowing from IP+ to IP- gives a positive output slope above VOQ. |
| 4 | IP- | passive | Negative terminal of the input current path (pins 3 and 4 tied); current flowing from IP+ to IP- gives a positive output slope above VOQ. |
| 5 | GND | power_in | Signal ground. |
| 6 | VZCR | output | Zero-current reference voltage output, fixed at 2.5V for VCC=4.5~5.5V in this fixed-output (BF5) version, independent of supply. |
| 7 | VOUT | output | Analog voltage output proportional to the input current; zero-current output VOQ is 2.5V for this bidirectional fixed-output 5V version. |
| 8 | VCC | power_in | Supply voltage input; 5V supply version (VCC=4.5~5.5V for fixed output mode). |
