Abstract

The ADC128S102QML-SP may display sparkle codes at the output of the device at an infrequent rate. A sparkle code is an erroneous output code that has a predictable output value and will only appear under specific input conditions. A more complete definition and description of a sparkle code is provided in this document. This application report provides background on the sparkle code behavior and provides empirical data across various device configurations and temperatures. From the data, it was found that a sparkle code occurrence is in the order of parts-per-billion over process and temperature. Also, the ADC128S102QML-SP design differs from the catalog version of the device and these design differences make the ADC128S102QML-SP susceptible to sparkle codes, whereas the catalog version of the device is not susceptible to sparkle codes.
