Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | -IN | input | Negative input of differential shunt voltage sensing pair, withstands common mode voltage -14V to +80V. |
| 2 | GND | power_in | Ground reference. |
| 3 | REF2 | input | Reference voltage input for output DC bias adjustment, accepts 0V to VGND+9V. |
| 4 | NC | unconnected | Not internally connected; may be left floating or connected to GND. |
| 5 | OUT | output | Output voltage proportional to input current at 100V/V gain setting, output impedance 1.5Ω. |
| 6 | V+ | power_in | Positive power supply, operating range +2.7V to +18V. |
| 7 | REF1 | input | Reference voltage input for output DC bias adjustment, accepts 0V to VGND+9V. |
| 8 | +IN | input | Positive input of differential shunt voltage sensing pair, withstands common mode voltage -14V to +80V. |
