DESCRIPTION
The PCM1716 is designed for Mid to High grade
Digital Audio applications which achieve 96kHz sam-
pling 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.
