DESCRIPTION
The 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
modulator employing 4th-order noise shaping and
8-level amplitude quantization. This design achieves
excellent
dynamic
performance
tolerance to clock jitter.
multilevel
delta-sigma
and
improved
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.
