DESCRIPTION
The PCM1738 is a CMOS, monolithic, integrated
circuit (IC) that includes stereo digital-to-analog
converters (DACs) and support circuitry in a small
SSOP-28 package. The data converters use a newly
developed advanced segment DAC architecture to
achieve excellent dynamic performance and
improved tolerance to clock jitter. The PCM1738
provides balanced current outputs, allowing the user
to optimize analog performance externally, and
accepts industry-standard audio data formats with
16- to 24-bit data, providing easy interfacing to audio
DSP and decoder chips. Sampling rates up to 200
kHz are supported. The PCM1738 also has two
optional modes of operation: an external digital filter
mode (for use with the DF1704, DF1706, and
PMD200), and a DSD decoder interface for SACD
playback applications. A full set of
user-programmable functions is accessible through a
4-wire serial control port that supports register write
and read functions.

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.

(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.
