模拟电子 校准ADC内部偏移的光学微控制器DS4830

Abstract: The DS4830 optical microcontroller's analog-to-digital converter (ADC) offset can change with temperature and gainselection. However, the DS4830 allows users to measure the ADC internal offset. The measured ADC offset is added to the ADCoffset register to nullify the offset error. Th ...

模拟电子 DAC技术用语 (D/A Converters Defini

Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...
