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.
