CS4384-DQZ中文资料凌云逻辑数据手册PDF规格书

Description

The CS4384 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 followed by an oversampled, multi-bit delta sigma modulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch. Follow ing this stage is a multi-element switched capacitor stage and low-pass filter with single-ended analog outputs.

The CS4384 also has a proprietary DSD processor which 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.
