DESCRIPTION
The PCM1792 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鈥檚 advanced segment DAC architecture
to achieve excellent dynamic performance and improved
tolerance to clock jitter. The PCM1792 provides balanced
current outputs, allowing the user to optimize analog
performance externally. The PCM1792 accepts PCM and
DSD audio data formats, providing easy interfacing to
audio DSP and decoder chips. The PCM1792 also
accepts to interface 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 I
2
C serial control port, which
supports register write and readback functions. The
PCM1792 also supports the time division multiplexed
command and audio (TDMCA) data format.
D
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.
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.
