AD637-EVALZ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

AD637-EVALZ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AD637-EVALZ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 AD637 is a complete, high accuracy, rms-to-dc converter that computes the true rms value of any complex waveform. It offers performance that is unprecedented in integrated circuit rms-to-dc converters and comparable to discrete and modular techniques in accuracy, bandwidth, and dynamic range. The AD637 computes the true root mean square, mean square, or absolute value of any complex ac (or ac plus dc) input waveform and gives an equivalent dc output voltage. The true rms value of a waveform is more useful than an average rectified signal because it relates directly to the power of the signal. The rms value of a statistical signal relates to the standard deviation of the signal.
