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 | Ref | input | Reference input. Drive with a low-impedance source; sets the output reference (zero) voltage. Swapping pins 1 and 3 will degrade CMR. |+| 2 | -In | input | Negative (inverting) input of the difference amplifier. Internally tied to the op amp inverting input through a 40kΩ resistor. |+| 3 | +In | input | Positive (non-inverting) input of the difference amplifier. Internally tied to the op amp non-inverting input through a 40kΩ resistor. |+| 4 | V- | power_in | Negative supply rail. Connect to ground for single-supply operation (2.7V to 36V) or to a negative rail for dual-supply operation (±1.35V to ±18V). |+| 5 | Sense | input | Sense input. Drive with a low-impedance source; typically tied to Output for standard difference-amp operation, or to a remote load node for Kelvin sensing. Swapping pins 2 and 5 will degrade CMR. |+| 6 | Output | output | Amplifier output. Unity-gain difference of (+In) - (-In) referenced to the Ref pin. Rail-to-rail swing within ~1V of V+ and 0.5V of V- with a 100kΩ load. |+| 7 | V+ | power_in | Positive supply rail. Accepts 2.7V to 36V single-supply or +1.35V to +18V dual-supply. |+| 8 | NC | unconnected | No internal connection. Leave floating (datasheet says 保持未连接 / keep unconnected). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `INA132UU`+- `INA132UUA`++## CAD (KiCad official)++- Symbol: `INA132U`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ina132) (24 pp, sha256 `4c07095c36dc4913`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
