DESCRIPTION
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.
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.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
