MAX1209Detailed DescriptionThe MAX1209 uses a 10-stage, fully differential,pipelined architecture (Figure 1) that allows for high-speed conversion whi

REFOUT sources up to 1.0mA and sinks up to 0.1mAfor external circuits with a load regulation of 35mV/mA.Short-circuit protection limits IREFOUTto a 2.
