Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Channel 1 analog output voltage, which swings to within a specified maximum of 30 mV of VS and 5 mV of GND. |
| 2 | IN-1 | input | Channel 1 current-sense amplifier negative input; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing, with common-mode range of -0.2 V to +26 V. |
| 3 | IN+1 | input | Channel 1 current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing, with common-mode range of -0.2 V to +26 V. |
| 4 | GND | power_in | Analog ground for the device. |
| 5 | IN+2 | input | Channel 2 current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side sensing or to the load side for low-side sensing, with common-mode range of -0.2 V to +26 V. |
| 6 | IN-2 | input | Channel 2 current-sense amplifier negative input; connect to the load side of the sense resistor for high-side sensing or to the ground side for low-side sensing, with common-mode range of -0.2 V to +26 V. |
| 7 | OUT2 | output | Channel 2 analog output voltage, which swings to within a specified maximum of 30 mV of VS and 5 mV of GND. |
| 8 | VS | power_in | Power supply pin; operating supply range is 2.7 V to 5.5 V. |
