An ADC and DAC Integral Non-Linearity (INL)
What is INL? This term describes the non-linearity of Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC). INL stands for Integral Non-Linearity. Is this term important? Should we...
View ArticleAn ADC and DAC Differential Non-Linearity (DNL)
As in the case of INL, DNL is an important parameter of an ADC or DAC because it is a measure of their non-linearity. DNL stands for Differential Non-Linearity and quantifies the ADC or DAC precision.

Most ADCs have a unipolar input range that can be a problem when designing bipolar circuits. Some common ADC input voltage ranges are 0 to 2.5 V, or 0 to 5 V. However, the analog circuit that drives...
View ArticleDesign a Unipolar to Bipolar Converter for a Unipolar Voltage Output DAC
Unipolar to bipolar converters are useful when we have to have a unipolar component to do a certain job in a mixed signal design environment. For example, Digital to Analog Converters (DACs) may have...
