Low Noise Constant Current Laser Controllers

The ATLSxA104 series laser drivers/controllers have ultra-low output noise, compact size, and come with current limit protection function. The output voltage is 0.5V to 3.6V when powered by a 5V power supply. The controller has temperature compensation network so that the output current maintains the same even as the controller temperature rises.
