Once a resistor is switched into circuit in this style converter, any further increases do not switch it out again. The structure is thus inherently monotonic, irrespective of inaccuracies in the resistors, and like the previous case, may be made intentionally non-linear where a specific non-linearity is required. Again like the previous case, the architecture is rarely, if ever, used to fabricate a complete DAC, because of the large numbers of resistors and switches required, but is often used as a component in a more complex DAC structure. Unlike the Kelvin divider, this type of DAC does not have a unique name, although both types are referred to as "fully decoded DACs" or "thermometer DACs".
