Abstract
A current steering digital to analog converter includes a current source for selectively providing a selected amount of current to an output in response to input data. The current source includes a selected number of sub-current sources for selectively providing fractions of the selected amount of current to the output. Compensation current sources each provide a selected amount of compensation current to the output. Compensation control circuitry, in response to the input data, selectively activates and de-activates selected ones of the sub-current sources and the compensation current sources to provide current compensation at the output.
