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 | OUT | output | Output current. Sourced through an external load resistor R_L to GND to develop the output voltage V_O = I_S * R_S * R_L / 5 kΩ. Output impedance ~1 GΩ || 5 pF; swings to within 0.8 V of V+ and V_CM. |+| 2 | GND | power_in | Device ground reference. |+| 3 | VIN+ | input | Positive differential sense input; connects to the high-voltage side of the external shunt resistor R_S. Common-mode range 2.7 V to 60 V (independent of V+). |+| 4 | VIN- | input | Negative differential sense input; connects to the load side of the external shunt resistor R_S. Full-scale sense voltage (VIN+ - VIN-) up to 500 mV. |+| 5 | V+ | power_in | Power supply input, 2.7 V to 60 V. Supply is independent of the input common-mode voltage. Quiescent current typically 25 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `INA168NAIDBVT`+- `INA168NAIDBVR`+- `INA168NANA`++## CAD (KiCad official)++- Symbol: `INA168NA`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (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/ina168.pdf) (28 pp, sha256 `381c48493d9daa2e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
