Abstract
An apparatus, system, and method are disclosed for testing an analog to digital converter with a known analog signal applied. A first register module stores a first digitized instance of an analog signal. A second register module stores a second digitized instance of the analog signal. A difference module calculates the absolute difference between the first and second digitized instances. A bad code module identifies an erroneous digitized instance wherein the absolute difference is greater than a limit value. In one embodiment, a counter module counts the erroneous digitized instance. A test system may identify a failed analog to digital converter if the erroneous digitized instance count is greater than a specified target value.
