DESCRIPTION

THD+N: 0.006% RL > 10 kΩ, Self-  
The PCM2704C/5C/6C/7C are TI's single-chip USB  
stereo audio digital-to-analog converters (DACs) with  
USB 2.0 compliant full-speed protocol controller and  
S/PDIF. The USB-protocol controller works with no  
software code, but USB descriptors can be modified  
in some areas (for example, vendor ID/product ID)  
through the use of an external ROM (PCM2704C/6C)  
or serial peripheral interface (SPI) (PCM2705C/7C).  
The PCM2704C/5C/6C/7C also employ SpAct™  
architecture, TI's unique system that recovers the  
audio clock from USB packet data. On-chip analog  
phase-locked loops (PLLs) with SpAct enable  
playback with low clock jitter.
