<Li> Hybrid DACs, which use a combination of the above techniques in a single converter . Most DAC integrated circuits are of this type due to the difficulty of getting low cost, high speed and high precision in one device . <Ul> <Li> The segmented DAC, which combines the thermometer - coded principle for the most significant bits and the binary - weighted principle for the least significant bits . In this way, a compromise is obtained between precision (by the use of the thermometer - coded principle) and number of resistors or current sources (by the use of the binary - weighted principle). The full binary - weighted design means 0% segmentation, the full thermometer - coded design means 100% segmentation . </Li> </Ul> </Li> <Ul> <Li> The segmented DAC, which combines the thermometer - coded principle for the most significant bits and the binary - weighted principle for the least significant bits .

Alternatively, a multiplying DAC takes a variable input voltage for their conversion . This puts additional design constraints on the bandwidth of the conversion circuit . </Li>
