I am working with an ASC758 current detector and an LTC1298 A/D converter. The ASC758 has a manufacturers "offset" so that at 0.0 amps the A/D will put out a digital reading of 483 representing this offset. So it seems to me that you would create a formula that looks like amps= ((reading-483) ** 8000) >>4. The highest output reading would be 2868. However at low readings such as 503 the results are still showing up as 0.0! Any ideas?
