DESCRIPTION  
The PCM1796 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 PCM1796 provides balanced  
current outputs, allowing the user to optimize analog  
performance externally. The PCM1796 accepts PCM and  
DSD audio data formats, providing easy interfacing to  
audio DSP and decoder chips. The PCM1796 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 or I2C serial control port, which  
supports register write and readback functions. The  
PCM1796 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.
