WebMar 29, 2024 · Mapping an A2D to a fixed-point data type. One way to map an A2D converter to a fixed-point data type is to use two real-world-value and stored-integer pairs. You then solve a pair of affine equations. realWorldValue1 = Slope * storedIntegerValue1 + Bias. realWorldValue2 = Slope * storedIntegerValue2 + Bias.
