## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Channel 1 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications. |
| 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. |
| 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 a common-mode range of -0.2 V to +26 V. |
| 4 | VS | power_in | Power supply pin, operating range 2.7 V to 5.5 V, which should be bypassed with at least 0.1 µF close to 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. |
| 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. |
| 7 | OUT2 | output | Channel 2 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications. |
| 8 | OUT3 | output | Channel 3 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications. |
| 9 | IN-3 | input | Channel 3 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. |
| 10 | IN+3 | input | Channel 3 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. |
| 11 | GND | power_in | Analog ground reference for the device; connect the ADC reference or microcontroller ground as close to this pin as possible. |
| 12 | IN+4 | input | Channel 4 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. |
| 13 | IN-4 | input | Channel 4 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. |
| 14 | OUT4 | output | Channel 4 analog output voltage of the current-sense amplifier, swinging between GND and VS as limited by the rail-to-rail output specifications. |
