Interfacing op amps to high-speed DACs, Part 2: Current-sourcing DACs
Most high-speed DACs are current-steering DACs that are designed with complementary outputs that either source or sink current. Part 1 of this three-part article series discussed the interface between a current sinking DAC and an op amp. This article, Part 2, discusses the interface between a current-sourcing DAC and an op amp. This interface allows the designer to use the full compliance voltage range of the DAC.
