DESCRIPTION

The DSD1796 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 DSD1796 provides balanced

current outputs, allowing the user to optimize analog

performance externally. The DSD1796 accepts the PCM

and DSD audio data formats, providing easy interfacing to

audio DSP and decoder chips. The DSD1796 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 an SPI serial control port, which

supports register write and readback functions. The

DSD1796 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.

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.

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.
