Checking A/D Converter Linearity

Without a Precision Reference. Statistical Technique Finds Missing Codes Quickly

The linearity of an analog-to-digital converter is usually measured by calibrating the ADC against a d/a converter that is at least 2 bits more accurate than the device under test. For example, a 10-bit ADC should be calibrated against (at least) a 12-bit converter. Read full article
