... REFERENCE CURRENT SET RESISTOR INTERNAL TO MAX5191 ONLY. USE EXTERNAL R must be pulled high with PD held at DGND. The MAX5188/MAX5191 typically require 50µs to wake up and allow both the outputs and the reference to settle. For lowest power consumption, the MAX5188/MAX5191 provide a power-down mode in which the reference, control amplifier, and current array are inactive and the DAC’ ...
