DESCRIPTION

ꢀ ACCEPTS 16-, 20-, AND 24-BIT AUDIO DATA

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.
