INA2180A1IDGKR from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

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).
