DESCRIPTION

The PCM1739 is a CMOS, monolithic, integrated

circuit which includes stereo 24-bit audio digital-to-

analog converters and support circuitry in a small

SSOP-28 package. The data converters utilize Burr-

Brown’s enhanced multi-level delta-sigma architec-

ture, which employs 4th-order noise shaping and

8-level amplitude quantization to achieve excellent

dynamic performance and improved tolerance to clock

jitter. The PCM1739 accepts industry-standard audio

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

interfacing to audio DSP and decoder chips. Sampling

rates up to 192kHz are supported.
