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.
