General Description

q ENHANCED MULTI-LEVEL ∆Σ DAC The PCM1732 is designed for mid- to high-grade q INPUT AUDIO DATA WORD: 16-, 20-, 24-Bit q SAMPLING FREQUENCY (fs): 16kHz - 96kHz q SYSTEM CLOCK: 256, 384, 512, 768fS q HIGH PERFORMANCE: THD+N: –96dB Dynamic Range: 104dB SNR: 104dB digital audio applications which achieve 96kHz sampling rates with 24-bit audio data, such as High Definition Compatible Digital (HDCD) CD players, DVD players, mini-disc players and AV receivers.

PCM1732 uses a newly-developed “enhanced, multilevel delta-sigma modulator” architecture that improves audio dynamic performance and reduces jitter q AUDIO OUTPUT LEVEL: 0.57 x VCC (Vp-p) q 8x OVERSAMPLING DIGITAL FILTER WITH HDCD DECODER: Stopband Attenuation: –120dB Passband Ripple: ±0.00001dB HDCD Filter Optimized for 44.1kHz to 48kHz sensitivity.

The internal digital filter operates at 8x oversampling at a 96kHz sampling rate, with –120dB stopband attenuation.
