AD8018ARU-EVAL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

AD8018ARU-EVAL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AD8018ARU-EVAL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。

PRODUCT DESCRIPTION

The AD8018 is intended for use in single-supply (5 V) xDSL modems where high-output current and low distortion are essential to achieve maximum reach. The dual high-speed amplifiers are capable of driving low distortion signals to within 0.5 V of the power supply rail.

FEATURES

Ideal xDSL Line Drive Amplifier for USB, PCMCIA, or

PCI-Based Customer Premise Equipment (CPE). The

AD8018 provides maximum reach on 5 V supply,

driving 16 dBm of power into a back-terminated,

transformer-coupled 100 Ω while maintaining –82 dBc

of out-of-band SFDR.
