The tables are a part of a feedforward control based on temperature which varies the value of the controlling signal as temperature changes. Introduction The DS1847 and DS1848 are digitally controlled resistors. The look-up tables in these parts are used to store Resistor positions that discretely compensate for the user’s application temperature de……
