AD8018ARU-EVAL屬于開(kāi)發(fā)板套件編程器的評(píng)估演示板及套件。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8018ARU-EVAL評(píng)估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過(guò)驗(yàn)證的實(shí)施環(huán)境中評(píng)估某些重點(diǎn)器件的性能或特性。評(píng)估方法通常有完善的文檔說(shuō)明，并且視乎具體情況由評(píng)估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點(diǎn)器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對(duì)于數(shù)量特別多或類別獨(dú)特的器件類別(如 ADC、DAC 和開(kāi)關(guān)模式電源)，評(píng)估平臺(tái)可組合為一個(gè)單獨(dú)的產(chǎn)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.
