INA2290A3IDGKR 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 | IN+1 | input | Current-sense amplifier positive input for channel 1; connect to the bus-voltage side of the channel 1 sense resistor. |
| 2 | IN-1 | input | Current-sense amplifier negative input for channel 1; connect to the load side of the channel 1 sense resistor. |
| 3 | IN+2 | input | Current-sense amplifier positive input for channel 2; connect to the bus-voltage side of the channel 2 sense resistor. |
| 4 | IN-2 | input | Current-sense amplifier negative input for channel 2; connect to the load side of the channel 2 sense resistor. |
| 5 | GND | power_in | Ground reference pin for the device. |
| 6 | OUT2 | output | Channel 2 output voltage. |
| 7 | OUT1 | output | Channel 1 output voltage. |
| 8 | VS | power_in | Power supply input; the recommended operating supply range is 2.7 V to 20 V. |
