INA199B2DCKR

Texas Instruments · Current-Sensing Amplifiers · SOT-363-6

INA199B2DCKR from Texas Instruments, in a SOT-363-6. 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 voltage input, 0 V to V+. Sets the output-voltage level that corresponds to zero differential input (VSENSE = 0), enabling bidirectional current sensing when biased to mid-supply (typically VS/2).
2 GND power_in Analog ground return for the device.
3 V+ power_in Analog power supply, 2.7 V to 26 V (absolute max 26 V). Independent of the sensed common-mode input voltage.
4 IN+ input Non-inverting analog input; connect to the supply side of the external shunt resistor. Common-mode range -0.1 V to 26 V for the B version, independent of V+.
5 IN- input Inverting analog input; connect to the load side of the external shunt resistor. Common-mode range -0.1 V to 26 V for the B version, independent of V+.
6 OUT output Analog voltage output. VOUT = REF + Gain × (VIN+ - VIN-); Gain = 100 V/V for the INA199B2. Swings to within 50 mV of V+ and 5 mV of GND with a 10-kΩ load.

CAD (KiCad official)

  • Symbol: INA199B2DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363-6 (KiCad packages3D, STEP)
  • 3D model files: ina199b2dckr-etched.step / ina199b2dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina199b2dckr.step / ina199b2dckr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (None pp, sha256 7aa8a4e2d65ee36a, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
