CDB4362A开发板套件编程器的评估板-数模转换器（DAC）规格书PDF中文资料

CDB4362A属于开发板套件编程器的评估板-数模转换器（DAC）。由凌云逻辑制造生产的CDB4362A评估板 - 数模转换器（DAC）该系列产品提供了一种方便的方法，在经过验证的设计环境中对用于将数字数据转换为模拟格式的器件进行性能或特性评估。重点器件涵盖范围从以适合学生或爱好者使用的方式实现的适度功能器件，到适合电信基础设施应用的高级器件。

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.
