When digital systems are used in real-world applications, it is often necessary to convert an analog voltage level to a binary number. The value of this number is directly or inversely proportional to the voltage. The analog-to-digital conversion is realized in the OPB Delta-Sigma ADC using Delta-Sigma conversion techniques. This core is designed to interface with the On-chip Peripheral Bus OPB).
