Working Principle
   
The AD8564ARZ is a dual comparator component, featuring a common non-inverting input, an output and two offset inputs. It is a voltage comparator, and it works by comparing the voltages at its two inputs. When the voltage at one of the inputs is higher than the voltage at the other input, the output will be high. Otherwise, the output will be low. 
   
This device provides some circuit protection features and stability against power supply noise, making it suitable for automation or control applications. The open-loop gain of the device can reach 1000V/mV, providing the user with a great accuracy and precision for comparison operations. Another useful feature of the AD8564ARZ is its chopper stabilized design, which prevents offset mismatch, providing the user with improved long-term reliability.
   
Summary
      
The AD8564ARZ is a low-power, chopper-stabilized dual comparator component, that is suitable for applications requiring high precision. It features low bias, low offset and low supply current, making it suitable for precision control applications. This device can be used in motion-control systems, data-conversion bridges, automotive systems and more. It works by comparing the voltage at its two inputs, and generating a high output when one of the input voltages is higher than the other.
