INA240A4DR

Texas Instruments · Current Sense Amplifiers · SOIC-8

INA240A4DR 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 Analog input connected to load side of shunt resistor with common-mode voltage range of -4V to 80V.
2 GND power_in Analog ground reference.
3 REF2 input Reference 2 voltage input, connect to 0V to VS for output midpoint adjustment.
4 NC unconnected No internal connection; may be grounded or left floating.
5 OUT output Analog output voltage representing sensed current with output swing from GND to VS.
6 VS power_in Power supply input with operating voltage range of 2.7V to 5.5V.
7 REF1 input Reference 1 voltage input, connect to 0V to VS for output midpoint adjustment.
8 IN+ input Analog input connected to source side of shunt resistor with common-mode voltage range of -4V to 80V.
