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 | RG | passive | Gain-set pin: the impedance between RG, REF (pin 5) and VOUT (pin 6) sets the gain as G = 5 + 5(R2/R1), and gain error from external resistors adds directly to the total error. |+| 2 | VIN- | power_in | Inverting signal input, diode-clamped to the supply rails; input signals that swing more than 0.5V beyond the rails should be limited to 10mA or less, and a bias-current return path must be provided. |+| 3 | VIN+ | power_in | Non-inverting signal input, diode-clamped to the supply rails; input signals that swing more than 0.5V beyond the rails should be limited to 10mA or less, and a bias-current return path must be provided. |+| 4 | V- | power_in | Negative power supply terminal; the device is specified for a total supply V+ to V- of +2.7V to +5.5V, and the supply should be decoupled with 0.1µF capacitors close to the device. |+| 5 | REF | input | Reference terminal that defines the zero output voltage level; it requires a low-impedance connection (as little as 160Ω in series degrades CMRR to 50dB) and must be at least 1.2V below the positive supply rail. |+| 6 | VOUT | output | Amplifier output, referred to the REF pin; it swings to within 25mV of the supply rails for gains of 10 or greater with loads above 10kΩ, and short-circuit current is specified as +48/-32 mA. |+| 7 | V+ | power_in | Positive power supply terminal; the device is fully specified from +2.7V to +5.5V with quiescent current of 490µA max per channel and must be at least 1.2V above the REF voltage. |+| 8 | Shutdown | input | Shutdown control, nominally connected to V+; pulling it below 0.8V on a 5V supply puts the amplifier into sleep mode (under 2µA draw), and the threshold varies with supply per the Shutdown Voltage vs Supply Voltage curve. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | MSOP-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `INA332AIDGKT`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)+- 3D model files: `ina332aidgkt-etched.step` / `ina332aidgkt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina332aidgkt.step` / `ina332aidgkt.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/ina2332) (24 pp, sha256 `3f90197e923b50a8`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
