EVAL-AD5243SDZ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-AD5243SDZ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-AD5243SDZ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 AD5243 and AD5248 provide a compact 3 mm × 4.9 mm packaged solution for dual, 256-position adjustment applications. The AD5243 performs the same electronic adjustment function as a 3-terminal mechanical potentiometer, and the AD5248 performs the same adjustment function as a 2-terminal variable resistor.
