24-Bit, 192kHz Sampling,
Advanced Segment, Audio-Stereo
DIGITAL-TO-ANALOG CONVERTER
PCM1738
DESCRIPTION
The PCM1738 is a CMOS, monolithic, Integrated Cir-
cuit (IC) that includes stereo Digital-to-Analog Convert-
ers (DACs) and support circuitry in a small SSOP-28
package. The data converters utilize a newly developed
advanced segment DAC architecture to achieve excel-
lent dynamic performance and improved tolerance to
clock jitter. The PCM1738 provides balanced current
outputs, allowing the user to optimize analog perfor-
mance 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 200kHz 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 are accessible through a 4-wire serial control
port that supports register write and read functions.
