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

INA190A3IDCKR 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 offset voltage and enables bidirectional current sensing when driven with an externally applied voltage. Recommended range: GND to VS.
2 GND power_in Ground reference for the device.
3 VS power_in Power supply input, 1.7 V to 5.5 V (absolute max 6 V). Bypass to GND with a 0.1 uF ceramic capacitor. Quiescent current ~65 uA (max).
4 IN+ input Current-sense amplifier positive input. For high-side applications, connect to the bus-voltage side of the sense resistor. For low-side applications, connect to the load side of the sense resistor. Common-mode range: -0.2 V to +40 V.
5 IN- input Current-sense amplifier negative input. For high-side applications, connect to the load side of the sense resistor. For low-side applications, connect to the ground side of the sense resistor.
6 OUT output Analog voltage output. Provides the gained-up voltage difference (IN+ minus IN-) times gain (100 V/V for A3), offset by the voltage applied to REF. Rail-to-rail output with 10 kOhm load.

Provenance

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

  • Datasheet: Texas Instruments datasheet (45 pp, sha256 1a17f09a74053f80, 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).
