 +===== Overview ===== 
 +[[http://​​CN0348|CN-0348]] showcases a solution for precision 16-bit digital-to-analog conversion with wide dynamic signal range in a single supply system. It utilizes a 5V voltage reference ([[http://​​ADR4550|ADR4550]]),​ a voltage output digital-to-analog converter ([[http://​​AD5541A|AD5541A]]), ​ and a rail-rail amplifier as the output buffer ([[http://​​ADA4500-2|ADA4500-2]]). The ADA4500-2 exhibits zero crossover distortion and this feature makes it an excellent choice as an output buffer to maintain the linearity of the AD5541A over its input digital code and provide a wide dynamic output range. The combination of parts provides industry-leading 16-bit integral nonlinearity (INL) of ±1LSB and differential nonlinearity (DNL) of ±1LSB with guaranteed monotonicity.  
 +This user guide gives information on how to use the evaluation software to collect data from the [[http://​​EVAL-CN0348-SDPZ|EVAL-CN0348-SDPZ]] Daughter Board.
