- Key Differences Between the PCM290x and PCM290xCPDF, 104 Kb, Archivo publicado: sept 14, 2011
This document presents the major differences between the PCM290xB and PCM290xC series audio data converters. - Solving Enumeration Errors in USB Audio DAC and CODEC DesignsPDF, 157 Kb, Archivo publicado: oct 30, 2009
TI’s portfolio of audio digital-to-analog converters (DACs) and coder/decoders (codecs) with integrated USB interfaces offers an excellent building block for any streaming USB audio system. When designing with the PCM270x and PCM29xx devices, careful attention must be given to both the clocking and USB hardware configurations in order to ensure proper host to device communication.This applicatio - Dyamic Performance Testing of Digital Audio D/A ConvertersPDF, 145 Kb, Archivo publicado: 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.
