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.

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.
