24-Bit, 192kHz Sampling

Enhanced Multi-Level, Delta-Sigma, Audio

DIGITAL-TO-ANALOG CONVERTER

PCM1737

TM

DESCRIPTION

The PCM1737 is a CMOS, monolithic, integrated

circuit which includes stereo digital-to-analog con-

verters and support circuitry in a small SSOP-28

package. The data converters utilize Burr-Brown’s

enhanced multi-level delta-sigma architecture, which

employs 4th-order noise shaping and 8-level ampli-

tude quantization to achieve excellent dynamic per-

formance and improved tolerance to clock jitter.

The PCM1737 accepts industry standard audio data

formats with 16- to 24-bit data, providing easy

interfacing to audio DSP and decoder chips. Sam-

pling rates up to 192kHz are supported. A full set

of user-programmable functions are accessible through

a 4-wire serial control port which supports register

write and read back functions.
