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 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
