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.
