INA190A1IRSWT

Texas Instruments · Current-Sensing Amplifiers · UQFN-10(1.4x1.8)

INA190A1IRSWT from Texas Instruments, in a UQFN-10(1.4x1.8). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected Not internally connected; float these pins or connect to any voltage between GND and VS.
2 NC unconnected Not internally connected; float these pins or connect to any voltage between GND and VS.
3 IN+ input Current-sense amplifier positive input; connect to the bus voltage side of the sense resistor for high-side applications or to the load side for low-side applications, with input pin voltage range GND - 0.2 V to 40 V.
4 IN- input Current-sense amplifier negative input; connect to the load side of the sense resistor for high-side applications or to the ground side for low-side applications, with input pin voltage range GND - 0.2 V to 40 V.
5 NC unconnected Not internally connected; float these pins or connect to any voltage between GND and VS.
6 VS power_in Power supply input, operating supply voltage 1.7 V to 5.5 V.
7 ENABLE input Digital enable input that must be driven externally or connected to VS if not used; driving it to VS turns the device on, while driving it to GND turns it off, reducing supply current and placing the output in high impedance, with ENABLE absolute maximum of GND - 0.3 V to 6 V.
8 REF input Reference input that enables bidirectional current sensing with an externally applied voltage within the range GND to VS.
9 GND power_in Analog ground.
10 OUT output Analog voltage output equal to the gained-up voltage difference from IN+ to IN-, offset by the voltage applied to the REF pin.

Provenance

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

  • Datasheet: Texas Instruments datasheet (45 pp, sha256 1a17f09a74053f80, retrieved 2026-11-02, 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: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
