ADN2847 - 3 V Dual-Loop 50 Mbps to 3.3 Gbps Laser Diode Driver

This page provides the datasheet information for the ADN2847, a member of the ADN 3 V Dual-Loop 50 Mbps to 3.3 Gbps Laser Diode Driver family.

Datasheet Summary

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.
