EVAL-AD5592R-1SDZ, Evaluation Board is designed to help customers quickly prototype the AD5592R-1 ADC/DAC/GPIO circuits. The AD5592R-1 operates from a single 2.7V to 5.5V supply and incorporates an internal 2.5V reference to give an output voltage span of 2.5V or 5V. An external reference(a 2.5V reference is provided on the evaluation board) can also be used to give an output from 0V to VREF or 0V to 2 + VREF
