Digital-to-analog converter switching circuitry

A method of performing digital-to-analog conversion, comprising the steps of:

• a) providing a first and a second digital-to-analog converter (DAC), each having a first output and a second output, wherein the first output of the first DAC is coupled to a first switch node, wherein the second output of the second DAC is coupled to a second switch node, wherein the second output of the first DAC is coupled to the first output of the second DAC at a common node;
• b) coupling the common node to the second switch node in response to a first switch signal;
• and
• c) coupling the common node to the first switch node in response to a second switch signal.

A digital-to-analog conversion circuit apparatus, comprising:

• first and second digital-to-analog converters (DAC), each having a first and a second output, wherein the second output of the first DAC is coupled to the first output of the second DAC at a common node, wherein the first output of the first DAC is coupled to a first switch node, wherein the second output of the second DAC is coupled to a second switch node;
• a first switch for coupling the common node to the first switch node;
• and
• a second switch for coupling the common node to the second switch node, wherein the DACs and switches are formed on a same integrated circuit die.
