Abstract: In a described example, a circuit includes a digital-to-analog converter (DAC) unit element switch circuit including first and second sign switch inputs, first and second select switch inputs, and first, second and third DAC outputs. Synchronizer logic includes a selection input and first and second synchronization outputs, in which the first synchronization output is coupled to the first select switch input and the second synchronization output is coupled to the second select switch input. Selection logic includes a data input, a sign control output and a selection control output, in which the sign control output is coupled to the first and second sign switch inputs, and the selection control output is coupled to the selection input.
