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- | input | Analog input connected to the load side of the shunt resistor; the differential input range is limited to -80 V to 80 V, with common-mode range of -4 V to 80 V. |+| 2 | GND | power_in | Analog ground; the device runs from a single supply (VS, 2.7 V to 5.5 V) referenced to this pin. |+| 3 | REF2 | input | Reference voltage 2, to be connected between 0 V and VS; it must not be driven below GND or above VS, and REF1 and REF2 may be tied together. |+| 4 | NC | unconnected | Not internally connected; reserved, and may be grounded or left floating. |+| 5 | OUT | output | Analog output voltage, swinging between GND and VS; it is limited to within GND - 0.3 V and VS + 0.3 V as an absolute maximum and can drive up to 1 nF of capacitive load without sustained oscillation. |+| 6 | VS | power_in | Power supply, 2.7 V to 5.5 V (absolute maximum 6 V), with a 0.1 µF bypass capacitor recommended close to the pin. |+| 7 | REF1 | input | Reference voltage 1, to be connected between 0 V and VS; it must not be driven below GND or above VS, and REF1 and REF2 may be tied together. |+| 8 | IN+ | input | Analog input connected to the supply side of the shunt resistor; the common-mode range is -4 V to 80 V, independent of VS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `INA240A3D`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `ina240a3d-etched.step` / `ina240a3d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina240a3d.step` / `ina240a3d.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ina240) (38 pp, sha256 `b75bb6d308520432`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
