# INA2180A3QDGKRQ1

**Texas Instruments** · Current Sense Amplifiers · VSSOP-8

INA2180A3QDGKRQ1 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; the output swings between GND and VS, with the datasheet specifying it within about 30 mV of VS and 5 mV of GND at RL = 10 kΩ. |
| 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. |
| 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 a common-mode range of -0.2 V to +26 V. |
| 4 | GND | power_in | Analog ground reference 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 a 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. |
| 7 | OUT2 | output | Channel 2 analog output voltage; the output swings between GND and VS, with the datasheet specifying it within about 30 mV of VS and 5 mV of GND at RL = 10 kΩ. |
| 8 | VS | power_in | Power supply, 2.7 V to 5.5 V; a bypass capacitor of at least 0.1 µF should be placed close to this pin. |
