DESCRIPTIONThe 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.
