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). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `INA2180A1IDGKRIDGKR`+- `INA2180A1IDGKRIDGKT`+- `INA2180A1IDGKRIDSGR`+- `INA2180A1IDGKRIDSGT`++## CAD (KiCad official)++- Symbol: `INA2180A1IDGKR`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/ina2180a1i.pdf) (50 pp, sha256 `271a5242291d4eca`, retrieved 2026-08-17, tier: manufacturer)+- **Datasheet language:** Chinese.
