Abstract
A composite digital-to-analog converter (DAC) includes a first DAC and a second DAC. The first DAC has a first range and a first error. The second DAC has a second range and a second error. The second range of the second DAC is less than the first range of the first DAC. The second range of the second DAC is greater than the first error of the first DAC. The second error of the second DAC is less than the first error of the first DAC. The composite DAC has a composite range and a composite error. The second DAC is coupled to minimize the composite error such that the composite range of the composite DAC is the first range and the composite error of the composite DAC is the second error.
