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. Sets the output voltage when the differential input (IN+ − IN−) is zero. Typically tied to GND for unidirectional sensing or driven to V+/2 for bidirectional sensing. Allowed range: GND-0.3 V to (V+)+0.3 V. |+| 2 | GND | power_in | Ground / negative supply return for the device. |+| 3 | V+ | power_in | Positive supply input, +2.7 V to +26 V. Quiescent current is 100 µA (max). A 0.01 µF to 0.1 µF bypass capacitor to GND is recommended. |+| 4 | IN+ | input | Non-inverting differential input. Connect to the load side (or high side, depending on topology) of the external current-sense resistor RSHUNT. Common-mode range -0.3 V to +26 V independent of V+. |+| 5 | IN- | input | Inverting differential input. Connect to the supply side of the external current-sense resistor RSHUNT. Common-mode range -0.3 V to +26 V independent of V+. |+| 6 | OUT | output | Analog voltage output. VOUT = REF + Gain × (IN+ − IN−); Gain = 50 V/V for the A1 variant. Rail-to-rail output, drives loads ≥ 10 kΩ to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-363(SC-70-6) |+| Category | Op-amp/Cmp |+| Pins | 6 |++## Ordering variants++- `INA199A1DCKRDCKR`+- `INA199A1DCKRDCKT`+- `INA199A1DCKRRSWR`+- `INA199A1DCKRRSWT`++## CAD (KiCad official)++- Symbol: `INA199A1DCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SOT-363(SC-70-6) (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/ina199a1.pdf) (28 pp, sha256 `f7222d6189aa059a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
