TEXAS INSTRUMENTS · Global Sourcing Parts · SOIC-8

INA241A5IDR from TEXAS INSTRUMENTS, in a SOIC-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 IN- input Current-sense amplifier negative input; connect to load side of sense resistor for high-side applications or ground side of sense resistor for low-side applications.
2 GND power_in Ground.
3 REF2 input Reference 2 voltage input; connect to a voltage potential from 0V to VS.
4 NC unconnected Reserved pin that the datasheet says to connect to ground (absolute maximum input range GND − 0.3V to VS + 0.3V).
5 OUT output Output voltage.
6 VS power_in Power supply, 2.7V to 20V.
7 REF1 input Reference 1 voltage input; connect to a voltage potential from 0V to VS.
8 IN+ input Current-sense amplifier positive input; connect to bus-voltage side of sense resistor for high-side applications or load side of sense resistor for low-side applications.
