EVAL-AD9838SDZ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

EVAL-AD9838SDZ属于开发板套件编程器的评估演示板及套件。由亚德诺半导体技术有限公司制造生产的EVAL-AD9838SDZ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。

GENERAL DESCRIPTION

The AD9838 is a low power DDS device capable of producing high performance sine and triangular outputs. It also has an on-board comparator that allows a square wave to be produced for clock generation. Consuming only 11 mW of power at 2.3 V, the AD9838 is an ideal candidate for power-sensitive applications.
