ADN2848ACP-32-RL7中文資料亞德諾數據手冊PDF規(guī)格書

GENERAL DESCRIPTION

The ADN2848 uses a unique control algorithm to control both the average power and the extinction ratio of the laser diode (LD) after initial factory setup. External component count and PCB area are low because both power and extinction ratio control are fully integrated. Programmable alarms are provided for laser fail (end of life) and laser degrade (impending fail).
