DESCRIPTION

The PCM1739 is a CMOS, monolithic, integrated
circuit which includes stereo 24-bit audio digital-to­analog converters and support circuitry in a small
SSOP-28 package. The data converters utilize Burr­Brown’s enhanced multi-level delta-sigma architec­ture, 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.

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
