THD+N Versus Frequency Characteristics and Spectra of the PCM1717/18/19/20/23/27
PDF, 107 Kb, 档案已发布: Sep 27, 2000
The following application bulletin describes the theory and actual performance of THD+N versus frequency characteristics for the PCM1717 series which include on-chip digital filters. The contents of this article apply to the PCM1717 and other devices which use the same digital filter architecture and delta-sigma DAC, such as PCM1718, PCM1719, PCM1720, PCM1723, and PCM1727.

A Low Noise, Low Distortion Design for Antialiasing and Anti-Imaging Filters
PDF, 62 Kb, 档案已发布: Sep 27, 2000
In any digitizing system, antialiasing and anti-imaging filters are used to prevent the signal frequencies from folding back around the sample frequency and causing false (or alias) signals from appearing in the signal we are attempting to digitize. Very often, these filters must be very complex, high order analog filters in order to do their job effectively.

Dyamic Performance Testing of Digital Audio D/A Converters
PDF, 145 Kb, 档案已发布: Oct 2, 2000
This application bulletin will provide the reader with an understanding of test methods for audio digital-to-analog converters (DACs). In particular, delta-sigma DACs require a special understanding due to the nature of their architecture.
