          The Digital ADC is a digital core which provides analog functionality with all the benefits of a digital design process: shorter design cycles, lower risk, established design and layout tools, digital test methodology, and portability across process technologies.
          The design is implemented with a small number of digital gates and only an LVDS input cell, a digital output cell and a handful of passive external components.
          The ADC provides up to 12 effective bits and up to 15 kHz of bandwidth making it ideal fit for both low frequency sensors and high-quality voice.
          The benefits of the digital implementation include low voltage and low power process technologies where it excels in portable applications.
          Alternative digital process technologies enable the Digital ADC to be used in high reliability and radiation hard environments where analog implementations are problematic.
