DESCRIPTION
The PCM1732 is designed for mid- to high-grade
digital audio applications which achieve 96kHz sam-
pling rates with 24-bit audio data, such as High Defi-
nition Compatible Digital (HDCD) CD players, DVD
players, mini-disc players and AV receivers.

pling rates with 24-bit audio data, such as High Defi-
nition Compatible Digital (HDCD) CD players, DVD
players, mini-disc players and AV receivers.
PCM1732 uses a newly-developed “enhanced, multi-
level delta-sigma modulator” architecture that im-
proves audio dynamic performance and reduces jitter
sensitivity.
