AD5162EVAL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

AD5162EVAL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AD5162EVAL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 AD5162 provides a compact 3 mm × 4.9 mm packaged solution for dual, 256-position adjustment applications. This device performs the same electronic adjustment function as a 3-terminal mechanical potentiometer. Available in four end-toend resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), this low temperature coefficient device is ideal for high accuracy and stability-variable resistance adjustments. The wiper settings are controllable through an SPI digital interface. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.1
