ADN2847集成電路（IC）的激光驅(qū)動(dòng)器規(guī)格書PDF中文資料

ADN2847屬于集成電路（IC）的激光驅(qū)動(dòng)器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADN2847激光驅(qū)動(dòng)器激光驅(qū)動(dòng)器電源管理集成電路 (PMIC) 可用于提供一個(gè)或多個(gè)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(guò)監(jiān)控受驅(qū)動(dòng)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(duì)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(lái)。

GENERAL DESCRIPTION

The ADN2847 uses a unique control algorithm to control both average power and extinction ratio of the laser diode (LD) after initial factory setup. External component count and PCB area are low, as both power and extinction ratio control are fully integrated. Programmable alarms are provided for laser fail (end of life) and laser degrade (impending fail).
