DESCRIPTION  
Passband Ripple: ±0.02 dB  
The DSD1608 is a CMOS, monolithic, 8-channel  
digital-to-analog converter which supports both PCM  
audio data format and direct stream digital (DSD) audio  
data format. The device includes an 8× digital  
interpolation filter and a digital DSD filter with three  
selectable frequency-response curves, followed by  
Texas Instruments’ enhanced multilevel delta-sigma  
modulator, which employs 4th-order noise shaping and  
8-level amplitude quantization to achieve excellent  
dynamic performance and improved tolerance to clock  
jitter. Sampling rates up to 192 kHz for the PCM mode  
and 64 × 44.1 kHz for the DSD mode are supported. A  
full set of user-programmable functions is accessible  
through a 4-wire serial control port, which supports  
register write and read functions. The DSD1608  
supports the time-division-multiplexed command and  
audio data (TDMCA) format. The DSD1608 is available  
in a 52-pin TQFP package.
