CS4384-CQZR集成電路（IC）的ADC/DAC-特殊用途規(guī)格書PDF中文資料

CS4384-CQZR屬于集成電路（IC）的ADC/DAC-特殊用途。由凌云邏輯制造生產的CS4384-CQZRADC/DAC - 特殊用途該產品族中的產品可用于模擬和數字表示的信息轉換，適用于特定用例，或集成了通用數據轉換器中不常見的其他功能。例如針對超聲或汽車雷達應用集成了低噪聲放大器和可變增益級的器件、注重音頻和視頻的產品、在段碼式顯示器上集成顯示測量值功能的器件、集成輸入輸出電氣隔離的器件等。

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.
