Evaluating the functionalities of a designed DAC printed circuit board

Digital-to-analog (D/A) and Analog-to-digital (A/D) converter constitute an essential link when digital devices interface with analog devices, and vice versa. They are important building blocks of any digital system, including both communication and noncommunication systems. A D/A converter is im...
