Description
The CS4398 is a complete stereo 24 bit/192 kHz 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 interpo-
lation filters followed by an oversampled multi-bit delta-
sigma modulator that includes mismatch shaping tech-
nology that eliminates distortion due to capacitor
mismatch. Following this stage is a multi-element
switched capacitor stage and low pass filter with differ-
ential analog outputs.
The CS4398 also has an proprietary DSD processor
that 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 CS4398 accepts PCM data at sample rates from
32 kHz to 216 kHz, DSD audio data, has selectable dig-
ital filters, consumes little power, and delivers excellent
sound quality.
