Analog Devices Inc. EVAL-CN0405-EB1Z电路评估板
Analog Devices EVAL-CN0405-EB1Z电路评估板可评估CN0405的性能，CN0405是一款带按钮控制的高压输出DAC。CN0405高压输出DAC提供了一种利用按钮控制数字电位器取代传统高压机械电位器的完整解决方案。CN0405电路集成了低压AD5116数字电位器、ADCMP371比较器以及ADP121低压差线性稳压器。该器件由VIN源供电，接受最高20V的输入电压。来自分压器R1和R2的电压通过一个30µA、低静态电流、低压差线性稳压器ADP121调节到3.3V。经调节的3.3V源将VDD电压供应给数字电位器AD5116和比较器ADCMP371。
The CN0405 circuit is powered from the VIN source and accepts an input voltage up to 20V. The voltage from the divider, R1 and R2, is regulated to 3.3V using the ADP121 30μA, low quiescent current, low dropout linear regulator. The regulated 3.3V supplies the VDD voltage to the AD5116 digital potentiometer and the ADCMP371 comparator.
