DESCRIPTION
The PCM1728 is designed for mid- to high-grade
digital audio applications which achieve 96kHz sampling
rates with 24-bit audio data. PCM1728 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
oversampling at a 96kHz sampling rate.
The PCM1728 has superior audio dynamic performance,
24-bit resolution, and 96kHz sampling, making
it ideal for mid- to high-grade audio applications
such as CD, DVD, and musical instruments.
