INA2180A2QDGKRQ1 from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

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.
