CDB4385屬于開發(fā)板套件編程器的評估板-數(shù)模轉(zhuǎn)換器（DAC）。由凌云邏輯制造生產(chǎn)的CDB4385評估板 - 數(shù)模轉(zhuǎn)換器（DAC）該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗證的設(shè)計環(huán)境中對用于將數(shù)字?jǐn)?shù)據(jù)轉(zhuǎn)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(xué)生或愛好者使用的方式實現(xiàn)的適度功能器件，到適合電信基礎(chǔ)設(shè)施應(yīng)用的高級器件。

描述 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.
