Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN+1 | input | Current-sense amplifier positive input for channel 1, connected to the bus-voltage side of the channel 1 sense resistor; the common-mode input range is 2.7 V to 120 V and analog input common-mode voltage is limited to -20 V to +122 V. |
| 2 | IN-1 | input | Current-sense amplifier negative input for channel 1, connected to the load side of the channel 1 sense resistor; analog input common-mode voltage is limited to -20 V to +122 V. |
| 3 | IN+2 | input | Current-sense amplifier positive input for channel 2, connected to the bus-voltage side of the channel 2 sense resistor; analog input common-mode voltage is limited to -20 V to +122 V. |
| 4 | IN-2 | input | Current-sense amplifier negative input for channel 2, connected to the load side of the channel 2 sense resistor; analog input common-mode voltage is limited to -20 V to +122 V. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | OUT2 | output | Channel 2 output voltage; the analog output is limited to GND - 0.3 V to VS + 0.3 V. |
| 7 | OUT1 | output | Channel 1 output voltage; the analog output is limited to GND - 0.3 V to VS + 0.3 V. |
| 8 | VS | power_in | Power supply, with a recommended operating supply range of 2.7 V to 20 V (absolute maximum 22 V). |
