CS4398是一个完善的立体声24位/192千赫数字至模拟(D/A)转换系统
The CS4398 is a complete stereo 24 bit/192 kHz digitalto-
analog system. This D/A system includes digital deemphasis,
half dB step size volume control, ATAPI
channel mixing, selectable fast and slow digital interpolation
filters followed by an oversampled multi-bit deltasigma
modulator that includes mismatch shaping technology
that eliminates distortion due to capacitor
mismatch. Following this stage is a multi-element
switched capacitor stage and low pass filter with differential
analog outputs.
The CS4398 also has an proprietary DSD processor
that allows for volume control and 50 kHz on-chip filtering
without an intermediate decimation stage. It also
offers an optional path for direct DSD conversion by directly
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 digital
filters, consumes little power, and delivers excellent
sound quality.
