Data Converter (A/D) Terminology
This application note describes a number of parameters related to "binary" and "lin- ear" data converters, as specified in Atmel's datasheets, and discusses to what point they can be tested. "Binary" means that the converter uses all binary code combina- tions. "Linear" means that there is no non-linearity other than that of quantization: all steps of the related ideal converters are equal in size. The following definitions assume that converters operate over their entire full-scale range, using a straight binary code format. Nevertheless, they can be easily adapted for converters operating over a limited range, or using another binary code format. In particular, binary-coded decimal (BCD) converters and floating-point (FP) converters are not considered in this document, because the first are ?non-binary" converters, and the later are ?non-linear" converters.
