CDB3318开发板套件编程器的评估演示板及套件规格书PDF中文资料

CDB3318属于开发板套件编程器的评估演示板及套件。由凌云逻辑制造生产的CDB3318评估和演示板及套件该系列产品提供了一种方便的方法，在经过验证的实施环境中评估某些重点器件的性能或特性。评估方法通常有完善的文档说明，并且视乎具体情况由评估软件提供支持。产品通常由印刷电路板组成，板上已装有重点器件以及必要或有用的支持元器件，另外也可能包括其他组件，例如电缆或电源。对于数量特别多或类别独特的器件类别(如 ADC、DAC 和开关模式电源)，评估平台可组合为一个单独的产品系列。

Description

The CS3318 is an 8-channel digitally controlled analog volume control designed specifically for high-end audio systems. It features a comprehensive I²C/SPI serial control port for easy device and volume configuration.

The CS3318 includes arrays of well-matched resistors and complementary low-noise active output stages. A total adjustable range of 118 dB, in ¼ dB steps, is spread evenly over 96 dB of attenuation and 22 dB of gain.

The CS3318 implements configurable zero-crossing detection to provide glitch-free volume-level changes.
