INA280A3QDCKRQ1

Texas Instruments · Current-Sensing Amplifiers · SC-70-5

INA280A3QDCKRQ1 from Texas Instruments, in a SC-70-5. 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 OUT output Output voltage pin, which must stay between GND - 0.3 V and VS + 0.3 V per the absolute maximum ratings.
2 GND power_in Ground reference pin for the device.
3 VS power_in Power supply pin, with a recommended operating supply range of 2.7 V to 20 V (absolute maximum 22 V).
4 IN+ input Connects to the supply side of the shunt resistor; common-mode voltage on the analog inputs is limited to -20 V to 122 V (absolute maximum).
5 IN- input Connects to the load side of the shunt resistor; differential input voltage between IN+ and IN- is limited to ±30 V (absolute maximum).
