Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Channel 1 analog output voltage. Delivers the amplified sense-resistor voltage (gain = 20 V/V) referenced to GND, with a 2 V/µs slew rate. Drive an ADC or comparator input. |
| 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 the ground side for low-side sensing. Common-mode range -0.2 V to +26 V. |
| 3 | IN+1 | input | Channel 1 current-sense amplifier positive input. Connect to the bus/supply side of the sense resistor for high-side sensing, or the load side for low-side sensing. Common-mode range -0.2 V to +26 V. |
| 4 | GND | power_in | Analog ground reference for both channels. Connect to the system analog ground plane. |
| 5 | IN+2 | input | Channel 2 current-sense amplifier positive input. Connect to the bus/supply side of the sense resistor for high-side sensing, or the load side for low-side sensing. Common-mode range -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 the ground side for low-side sensing. Common-mode range -0.2 V to +26 V. |
| 7 | OUT2 | output | Channel 2 analog output voltage. Delivers the amplified sense-resistor voltage (gain = 20 V/V) referenced to GND, with a 2 V/µs slew rate. Drive an ADC or comparator input. |
| 8 | VS | power_in | Positive power supply, 2.7 V to 5.5 V. Bypass to GND with a 0.1 µF ceramic capacitor placed close to the pin. Maximum quiescent current 500 µA (dual channel). |
