INA241A4IDDFR

Texas Instruments · Current Sense Amplifiers · TSOT-23-8

INA241A4IDDFR from Texas Instruments, in a TSOT-23-8. 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; for high-side applications connect to the load side of the sense resistor, and for low-side applications connect to the ground side of the sense resistor.
2 GND power_in Ground reference pin for the device.
3 REF2 input Reference 2 voltage input; connect to a voltage potential from 0 V to VS.
4 NC unconnected Reserved pin; the datasheet says to connect it to ground.
5 OUT output Amplifier output voltage.
6 VS power_in Power supply input, 2.7 V to 20 V.
7 REF1 input Reference 1 voltage input; connect to a voltage potential from 0 V to VS.
8 IN+ input Current-sense amplifier positive input; for high-side applications connect to the bus-voltage side of the sense resistor, and for low-side applications connect to the load side of the sense resistor.
