LEVERAGING FPGA AND CPLD DIGITAL LOGIC TO IMPLEMENT ANALOG TO DIGITAL CONVERTERS

An Analog to Digital Converter (ADC) is a common analog building block and almost always is needed when interfacing digital logic, like that in an FPGA or CPLD, to the “real world” of analog sensors.
This white paper will explain the implementation of both a low frequency (DC to 1K Hz) and higher frequency (up to 50K Hz) ADC using reference designs and demo boards available from Lattice Semiconductor. A sample application for each design: one for a system monitor in a network switch, and another for frequency detection in an audio communication system, will be examined.
