DESCRIPTION
The PCM1716 is designed for Mid to High grade
Digital Audio applications which achieve 96kHz sampling rates with 24-bit audio data. PCM1716 uses a
newly developed, enhanced multi-level delta-sigma
modulator architecture that improves audio dynamic
performance and reduces jitter sensitivity in actual
applications.
The internal digital filter operates at 8x over sampling
at a 96kHz sampling rate, with two kinds of roll-off
performances that can be selected: sharp roll-off, or
slow roll-off, as required for specific applications.
PCM1716 is suitable for Mid to High grade audio
applications such as CD, DVD-Audio, and Music
Instruments, since the device has superior audio
dynamic performance, 24-bit resolution and 96kHz
sampling.

PACKAGE INFORMATION
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.
