APPLICATIONS Universal A/V Players SACD Players Car Audio Systems Other Applications Requiring 24-Bit Audio DESCRIPTIONThe DSD1702 is a CMOS, monolithic, stereo
digital-to-analog converter that supports both PCM
audio data format and direct stream digital (DSD) audio
data format.
The device includes an 8x digital interpolation filter for
PCM signals. A digital DSD filter provides three different
selectable frequency response options, followed by
Burr-Brown’s enhanced multilevel delta-sigma
modulator employing 4th-order noise shaping and
8-level amplitude quantization. This design achieves
excellent dynamic performance and improved
tolerance to clock jitter.
DSD1702 sampling rates of up to 192 kHz for PCM
mode and 44.1 kHz × 64 for DSD mode are supported.
A full set of user-programmable functions is accessible
through a 3-wire serial control port, supporting register
write functions.
The DSD1702 is available in a 20-lead QSOP package.
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate
precaustions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
