PCM Data Formats: Standard, I S, and  
The PCM1791A 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 PCM1791A  
provides balanced voltage outputs, allowing the user to  
optimize analog performance externally. The PCM1791A  
accepts PCM and DSD audio data formats, providing easy  
interfacing to audio DSP and decoder chips. The  
PCM1791A also accepts interface to 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 or I2C serial control  
port, which supports register write and readback functions.  
The PCM1791A 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.  
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.
