Laser driver: ATLSXA202D
It comes with a high stability low noise 2.5V voltage reference output which can be used for setting the output current. The reference output can also be used for the ADCs (Analog to Digital Converters) and/or DACs (Digital to Analog Converters) to monitor the laser output current and/or set laser output current respectively. They are designed for driving laser diodes with low noise constant current at high efficiency. The "xA" in the part number specifies the maximum output current of the laser controller, it can be chosen to be: 500mA, 1A, 2A, 3A, 4A or 6A. The module is packaged in a metal enclosure, emitting zero EMI, and has DIP mounting package. These laser drivers are of 100 % lead (Pb)-free and RoHS compliant.
