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 pin. Sources a current proportional to (V_IN+ − V_IN−); an external load resistor R_L to GND converts this to an output voltage V_O = I_S × R_S × R_L / 1kΩ, setting a gain of 1 to >100. |+| 2 | GND | power_in | Device ground reference. |+| 3 | VIN+ | input | Positive input voltage. Connects to the more positive end of the external current-sense shunt resistor R_S on the high side of the load. Common-mode range 2.7 V to 60 V for the INA169. |+| 4 | VIN- | input | Negative input voltage. Connects to the load side of the external sense resistor R_S. Differential input (VIN+ − VIN−) sets the output current through internal 1 kΩ resistors. |+| 5 | V+ | power_in | Power supply voltage. 2.7 V to 60 V operating range for the INA169; independent of the input common-mode voltage. Quiescent current ~60 µA typical. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Amplifiers/Comparators |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `INA169NA`++## CAD (KiCad official)++- Symbol: `INA169NA`+- 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/ina169.pdf) (28 pp, sha256 `dbb74b6cdc543135`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
