RoHS COMPLIANTDESCRIPTION:
AMI’s Model 763 OEM seed laser diode driver is ideal for driving 14-pin butterfly packaged laser
diode modules for use in CW or pulsed fiber MOPA systems. Applications include materials processing,
LIDAR systems for remote sensing, fiber optic temperature sensing, laser communication andrangefinding. The driver is implemented as a transconductance amplifier (analog voltage in, scaled
current out). The driver circuitry operates from a single 5V power source. All other needed voltages aregenerated on the board by high efficiency switching power supplies. The 763 is manufactured to theRoHS Directive 2002/95/EC requirements. All required mating cables are included.

On-board TEC Controller will provide heating and cooling as necessary to maintain desired operating
point. Thermistor and the TE cooler are in the laser diode package (not included). Customer may
need to provide thermal mass and/or forced air for heatsinking under high dissipation conditions.
