Description
The CS4385 is a complete 8-channel digital-to-analog
system. This D/A system includes digital de-emphasis,
half-dB step size volume control, ATAPI channel mixing,
selectable fast and slow digital interpolation filters fol-
lowed by an oversampled, multi-bit delta sigma
modulator which includes mismatch shaping technology
that eliminates distortion due to capacitor mismatch. Fol-
lowing this stage is a multi-element switched capacitor
stage and low-pass filter with differential analog outputs.
The CS4385 also has a proprietary DSD processor
which allows for volume control and 50 kHz on-chip filter-
ing without an intermediate decimation stage. It also
offers an optional path for direct DSD conversion by di-
rectly using the multi-element switched capacitor array.
The CS4385 accepts PCM data at sample rates from
4 kHz to 216 kHz, DSD audio data, and delivers excel-
lent sound quality. These features are ideal for multi-
channel audio systems including SACD players, A/V re-
ceivers,
digital
TV’s,
mixing
processors, sound cards and automotive audio systems.
