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.
