Title: Segmented resistor string digital-to-analog converters

Abstract: Segmented resistor string digital-to-analog converters using a resistor string primary converter segment and a current source secondary. The primary converter segment provides conversion of the most significant bits to an analog voltage form and the current source provides conversion of the least significant bits to an analog current form. An output circuit combines the two into a single analog output. Various embodiments are disclosed.
