CDB4385屬于開發(fā)板套件編程器的評估板-數模轉換器（DAC）。由凌云邏輯制造生產的CDB4385評估板 - 數模轉換器（DAC）該系列產品提供了一種方便的方法，在經過驗證的設計環(huán)境中對用于將數字數據轉換為模擬格式的器件進行性能或特性評估。重點器件涵蓋范圍從以適合學生或愛好者使用的方式實現的適度功能器件，到適合電信基礎設施應用的高級器件。

Description

The CS4385 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. Following this stage is a multi-element switched capacitor stage and low-pass filter with differential analog outputs.
