APPLICATIONS

DESCRIPTION

The DSD1792 is a monolithic CMOS integrated circuit that

includes stereo digital-to-analog converters and support

circuitry in a small 28-lead SSOP package. The data

converters use TI’s advanced-segment DAC architecture

to achieve excellent dynamic performance and improved

tolerance to clock jitter. The DSD1792 provides balanced

current outputs, allowing the user to optimize analog

performance externally. The DSD1792 accepts the PCM

and DSD audio data formats, providing easy interfacing to

audio DSP and decoder chips. The DSD1792 also

interfaces with external digital filter devices (DF1704,

DF1706, PMD200). Sampling rates up to 200 kHz are

supported. A full set of user−programmable functions is

accessible through a 4-wire serial control port, which

supports register write and readback functions. The

DSD1792 also supports the time-division-multiplexed

command and audio (TDMCA) data format.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate

precautions. 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.
