... For general applications, the ACPL-C79A (±1% gain tolerance) and the ACPL-C790 (±3% gain tolerance) are recommended. For high precision applications, the ACPL-C79B (±0.5% gain tolerance) can be used. The product operates from a single 5 V supply and provides excellent linearity and dynamic performance SNR. ...

The voltage from the current sensing resistor, or shunt (R the input of the ACPL-C79B/C79A/C790 through an RC anti-aliasing filter (R5 and C3). And finally, the differential output of the isolation amplifier is converted to a ground- referenced single-ended output voltage with a simple differential amplifier circuit (U3 and associated com- ponents) ...

... The Kelvin connections to the resistor should be brought together under the body of the resistor and then run very close to each other to the input of the ACPL-C79B/C79A/ C790; this minimizes the loop area of the connection and reduces the possibility of stray magnetic fields from inter- fering with the measured signal ...
