DESCRIPTION
The DSD1794 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 DSD1794 provides balanced
current outputs, allowing the user to optimize analog
performance externally. The DSD1794 accepts the PCM
and DSD audio data formats, providing easy interfacing to
audio DSP and decoder chips. The DSD1794 also
interfaces with external digital filter devices (DF1704,
DF1706, PMD200). Sampling rates up to 200 kHz are
supported. A full set of user鈭抪rogrammable functions is
accessible through an I
2
C-compatible serial port.
D
Accepts 16-, 20-, and 24-Bit Audio Data

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.
