INA186A1IDCKR

Texas Instruments · Current-Sensing Amplifiers · SC-70-6

INA186A1IDCKR from Texas Instruments, in a SC-70-6. 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 input. Sets the output voltage offset to enable bidirectional current sensing; drive with an external voltage (typically VS/2 for bidirectional, GND for unidirectional). Available only in DCK (SC70) and DDF (SOT-23) packages.
2 GND power_in Device ground / analog return.
3 VS power_in Power supply input, 1.7 V to 5.5 V. Bypass to GND with a 0.1 µF capacitor.
4 IN+ input Non-inverting current-sense input. Connect to the bus-side of the shunt resistor for high-side sensing, or to the load-side for low-side sensing. Common-mode range -0.2 V to +40 V, independent of VS.
5 IN- input Inverting current-sense input. Connect to the load-side of the shunt resistor for high-side sensing, or to ground-side for low-side sensing.
6 OUT output Analog voltage output. VOUT = (VIN+ - VIN-) × Gain + VREF. Gain is 25 V/V for the INA186A1 variant.

Provenance

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

  • Datasheet: Texas Instruments datasheet (47 pp, sha256 1517831c6395c89f, retrieved 2026-08-17, tier: lcsc)
  • 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).
