INA199A2DCKR

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

INA199A2DCKR 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; sets the output when V_SENSE = 0. Valid range 0 V to V+. Typically tied to GND (unidirectional) or V+/2 (bidirectional sensing).
2 GND power_in Device ground / negative supply reference.
3 V+ power_in Positive power supply, 2.7 V to 26 V. Bypass with 0.01 µF to 0.1 µF ceramic capacitor to GND. Quiescent current 100 µA (max).
4 IN+ input Non-inverting analog input; connect to the supply side of the external shunt resistor. Common-mode input range -0.3 V to 26 V (independent of V+).
5 IN- input Inverting analog input; connect to the load side of the external shunt resistor. Differential input range -26 V to +26 V (abs max).
6 OUT output Analog voltage output = REF + G × (V_IN+ − V_IN-). For INA199A2, gain G = 100 V/V. Rail-to-rail output stage; drives up to ~1 nF load without oscillation.

CAD (KiCad official)

  • Symbol: INA199A2DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363-6 (KiCad packages3D, STEP)
  • 3D model files: ina199a2dckr-etched.step / ina199a2dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina199a2dckr.step / ina199a2dckr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (35 pp, sha256 c2346bb59a217ea6, retrieved 2026-08-17, tier: manufacturer)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
