A REF pin sets the zero-current point for bidirectional current, and fixed-gain options (50, 100, 200 V/V) plus low offset make it accurate at small shunt voltages. It runs from a single 2.7 to 5.5 V rail. A small, precise current monitor for compact boards.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | REF | input | Reference voltage input, 0 V to V+. Sets the output bias for bidirectional current sensing. |+| 2 | GND | power_in | Device ground. |+| 3 | V+ | power_in | Power supply input, 2.7 V to 26 V. Quiescent current 100 uA max. Bypass with 0.01 uF to 0.1 uF to GND. |+| 4 | IN+ | input | Positive analog input. Connect to the supply side of the external shunt resistor. Common-mode range -0.3 V to 26 V (INA199Ax) or -0.1 V to 26 V (INA199Bx/Cx). |+| 5 | IN- | input | Negative analog input. Connect to the load side of the external shunt resistor. |+| 6 | OUT | output | Analog output voltage. Output = gain (50/100/200 V/V) x differential shunt voltage, biased around REF. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Current-sense amplifier (voltage output) |+| Common-mode range | -0.3 V to 26 V |+| Gain options | 50 / 100 / 200 V/V |+| Direction | Bidirectional (via REF) |+| Offset | Low (uV-class) |+| Supply | 2.7-5.5 V |+| Package | SC70-6 |++## Ordering variants++- `INA199A1DCKR (gain 50)`+- `INA199A2DCKR (gain 100)`+- `INA199A3DCKR (gain 200)`++## CAD (KiCad official)++- Symbol: `Amplifier_Current:INA199xxDCK (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC70-6 (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/ina199.pdf) (42 pp, sha256 `80b0656c17984904`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
