INA190A2QDCKRQ1

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

INA190A2QDCKRQ1 from Texas Instruments, in a SC-70-6. 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 REF input Reference input that enables bidirectional current sensing with an externally applied voltage, with a reference pin voltage range of GND to VS.
2 GND power_in Analog ground.
3 VS power_in Analog power supply, 1.7 V to 5.5 V.
4 IN+ input Current-sense amplifier positive input; connect to the bus-voltage side of the sense resistor for high-side use or the load side for low-side use, with an input pin voltage range of GND - 0.2 V to 40 V.
5 IN- input Current-sense amplifier negative input; connect to the load side of the sense resistor for high-side use or the ground side for low-side use, with an input pin voltage range of GND - 0.2 V to 40 V.
6 OUT output Analog output providing the gained-up voltage difference from IN+ to IN-, offset by the voltage applied to the REF pin.
