1. Pin 1 (IN+): Positive input for the differential voltage measurement.
2. Pin 2 (IN-): Negative input for the differential voltage measurement.
3. Pin 3 (V-): Negative supply voltage (ground).
4. Pin 4 (GND): Ground reference.
5. Pin 5 (OUT): Output voltage proportional to the current measurement.
6. Pin 6 (REF): Reference voltage for output, can be used for level shifting.
7. Pin 7 (V+): Positive supply voltage.
8. Pin 8 (NC): No connection (not used).
This configuration allows for simple integration into current measurement applications in various electronic systems.
