Analog Devices ADN2830 Continuous Wave Laser Average Power Controller Datasheet
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.
