The ADN2830 provides closed-loop control of the average optical power of a continuous wave (CW) laser diode (LD) after initial factory setup. The control loop adjusts the laser IBIAS to maintain a constant back facet monitor photodiode (MPD) current and thus a constant laser optical power. The external PSET resistor is adjusted during factory setup to set the desired optical power. RPSET is set at 1.23/IAV, where IAV is the MPD current corresponding to the desired optical power. Programmable alarms are provided for laser fail (end of life) and laser degrade (impending fail).
