The PCM1728 is a 24-bit, 96kHz sampling CMOS Delta-Sigma stereo digital-to-analog converter designed for mid- to high-grade digital audio applications. It utilizes a newly developed enhanced multi-level delta-sigma modulator architecture that improves audio dynamic performance and reduces jitter sensitivity in actual applications. The PCM1728 features 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.
The PCM1728 is designed for mid- to high-grade digital audio applications achieving 96kHz sampling rates with 24-bit audio data. It utilizes a newly developed, enhanced multi-level delta-sigma modulator architecture that improves audio dynamic performance and reduces jitter sensitivity in actual applications.
Key features include an internal digital filter operating at 8X oversampling, superior audio dynamic performance with 106dB SNR, and +5V single supply operation. The device is available in a small 28-lead SSOP package.
| Resolution | 24 Bits |
|---|---|
| Input Audio Data Word | 16-, 20-, 24-Bit |
