CDB4362A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CDB4362A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。

描述 Description

The CS4362A is a complete 6-channel digital-to-analog system. This D/A system includes digital de-emphasis, 1 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.

The CS4362A also has a proprietary DSD processor which allows for 50 kHz on-chip filtering without an intermediate decimation stage. The CS4362A is available in a 48-pin LQFP package in both Commercial (-40°C to +85°C) and Automotive grades (-40°C to +105°C). The CDB4362A Customer Demonstration board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 48 for complete details.

The CS4362A accepts PCM data at sample rates from 4 kHz to 216 kHz, DSD audio data, and delivers excellent sound quality. These features are ideal for multi channel audio systems including SACD players, A/V receivers, digital TV’s, mixing consoles, effects processors, sound cards, and automotive audio systems.
