Digital-to-analog converter circuitry

A circuit comprising:

• a plurality of digital-to-analog converter (DAC) unit elements, in which each DAC unit element includes:
• a unit element switch circuit configured to provide one of three values responsive to first and second sign output signals and first and second synchronization selection signals;
• synchronizer logic configured to provide the first and second synchronization selection signals responsive to a selection signal;
• sign logic configured to provide the first and second sign output signals responsive to a sign control signal;
• and
• selection logic configured to divide the plurality of DAC unit elements into first and second segments and to provide the selection signal and the sign control signal to route input data to at least one DAC unit element of a given one of the first and second segments such that consecutive overlap transitions are prevented.

An apparatus comprising:

• a digital interface including a digital input and a digital output;
• a digital filter including a filter input and a filter output, in which the filter input is coupled to the digital output;
• selection logic including a data input, a selection output, and a sign output, in which the data input is coupled to the filter output;
• a synchronizer logic circuit including a selection input, a clock input, and first and second synchronization outputs, in which the selection input is coupled to the selection output;
• a sign logic circuit including a sign input and first and second sign control outputs, in which the sign input is coupled to the sign output;
• and
• a digital-to-analog converter (DAC) unit element circuit including first and second sign switch inputs, first and second select switch inputs, and a DAC output, in which the first select switch input is coupled to the first synchronization output, the second select switch input is coupled to the second synchronization output, the first sign switch input is coupled to the first sign control output, and the second sign switch input is coupled to the second sign control output.
