The INA240A3QDRQ1: It measures the voltage drop across a shunt resistor on the high side or low side of a load, converting it to a ground-referenced output.
The AEC-Q100 qualification and the 8-SOIC package mean it is a drop-in for existing automotive current-sense BOM positions that use the same footprint.
The INA240A3QDRQ1 is a fixed-gain variant of the INA240 family. The gain value is a device-specific parameter — the datasheet lists the exact gain for this A3 suffix. The part number suffix encodes the gain option; confirm the gain against the BOM requirement before ordering.
The listing shows the package as Bulk. Tape-and-reel packaging may be available under a different order code suffix — verify the reel option against the distributor's inventory or request it in the RFQ notes.
