ADN2841 Datasheet (Analog Devices) - Dual-Loop 50 Mbps.2.7 Gbps Laser Diode Driver

ADN2841, Dual-Loop 50 Mbps.2.7 Gbps Laser Diode Driver

The ADN2841 uses a unique control algorithm to control both the average power and extinction ratio of the laser diode (LD) after initial factory setup.

Because power and extinction ratio control are fully integrated, external component count is low and PCB area is small.

Programmable alarms are prov
