Analog-to-Digital Converters are devices that convert analog signal to digital signal. These devices come in different resolutions and performance to fit various applications. This circuit is an evaluation board that helps users to assess the ADC121C021s’ performance. The ADC121C021 is a 12-bit ADC that runs with a +2.7-5.5V power supply. The converter is based upon successive approximation register architecture with internal track-and-hold circuit that can handle input frequencies up to 11MHz. This device is powered by a single supply, which also serves as the devices’ voltage reference. Read more
