INA290A3QDCKRQ1

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

INA290A3QDCKRQ1 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 of the current-sense amplifier; the absolute maximum output range is GND - 0.3 V to VS + 0.3 V.
2 GND power_in Ground reference pin for the device.
3 VS power_in Power supply pin; recommended operating supply range is 2.7 V to 20 V (5 V nominal), with an absolute maximum of 22 V.
4 IN+ input Connect to the supply side of the shunt resistor; analog inputs are rated for common-mode voltage from -20 V to 122 V and differential voltage of ±30 V (absolute maximum).
5 IN- input Connect to the load side of the shunt resistor; analog inputs are rated for common-mode voltage from -20 V to 122 V and differential voltage of ±30 V (absolute maximum).
