CS4351-CZZ集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

CS4351-CZZ属于集成电路（IC）的ADC/DAC-特殊用途。由凌云逻辑制造生产的CS4351-CZZADC/DAC - 特殊用途该产品族中的产品可用于模拟和数字表示的信息转换，适用于特定用例，或集成了通用数据转换器中不常见的其他功能。例如针对超声或汽车雷达应用集成了低噪声放大器和可变增益级的器件、注重音频和视频的产品、在段码式显示器上集成显示测量值功能的器件、集成输入输出电气隔离的器件等。

描述 Description

The CS4351 is a complete stereo digital-to-analog system including digital interpolation, fifth-order multi-bit delta-sigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing, analog filtering, and on-chip 2 Vrms line-level driver. The advantages of this architecture include ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature, high tolerance to clock jitter, and a minimal set of external components.

The CS4351 is available in a 20-pin TSSOP package in both Commercial (-10°C - +70°C) and Automotive grades (-40°C to +85°C). The CDB4351 Customer Demonstration board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 37 for complete details.

These features are ideal for cost-sensitive, 2-channel audio systems including DVD players, A/V receivers, set-top boxes, digital TVs and VCRs, mini-component systems, and mixing consoles.
