ADN2526屬于集成電路（IC）的激光驅(qū)動器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADN2526激光驅(qū)動器激光驅(qū)動器電源管理集成電路 (PMIC) 可用于提供一個或多個受控電流源，以從標(biāo)稱恒定電壓電源為半導(dǎo)體激光器件供電。產(chǎn)品通常支持通過監(jiān)控受驅(qū)動的激光器件發(fā)出的光功率而得到反饋，可廣泛應(yīng)用于光通信系統(tǒng)中；并因具有對提供給用電設(shè)備的電流進(jìn)行高頻調(diào)制的能力，而與執(zhí)行類似功能的器件區(qū)分開來。

GENERAL DESCRIPTION

The ADN2526 laser diode driver is designed for direct modulation of packaged laser diodes that have a differential resistance ranging from 5 ? to 50 ?. The active back-termination in the ADN2526 absorbs signal reflections from the TOSA end of the output transmission lines, enabling excellent optical eye quality to be achieved even when the TOSA end of the output transmission lines is significantly misterminated. ADN2526 is an SFP+ MSA-compliant device, and its small package and enhanced ESD protection provide the optimum solution for compact modules where laser diodes are packaged in low pin-count optical subassemblies.
