The ADN2830 is a closed-loop controller for the average optical power of a continuous wave (CW) laser diode (LD). It provides a bias current range of 4 mA to 200 mA, a monitor photodiode current of 50µA to 1200µA, and laser fail and degrade alarms. It also supports automatic laser shutdown, ALS, full current parameter monitoring and 5 V operation. It is suitable for fiber optic communication applications.
The ADN2830 provides closed-loop control of the average optical power of a continuous wave (CW) laser diode. It adjusts the laser bias current to maintain a constant back facet monitor photodiode current, ensuring stable optical output over time and temperature variations.
Key features include programmable alarms for laser fail and degradation, automatic laser shutdown capability, and full current parameter monitoring. The device operates from a 5V supply within an industrial temperature range of -40°C to +85°C.
