ADN2830ACPZ32
UnknownAVERAGE POWER CONTROLLER FOR CONTINUOUS WAVE (CW) LASER
Description
General part information
ADN2830 Series
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 Photo Diode (MPD) current and hence a constant laser optical power. The external PSET resistor is adjusted during factory set up to set the desired optical power. RPSETis set at 1.23/IAV, where IAVis the MPD current corresponding to the desired optical power. Programmable alarms are provided for laser fail (end of life) and laser degrade (impending fail).The ADN2830 operates from a single power +5 V supply. It is available in 5mm × 5mm LFCSP-32 Lead Frame Chip Scale.
