Our main products include TEC controllers, laser drivers, TEC module, thermistors, high voltage power supply and so on. Now I will introduce a low noise constant current laser driver ATLSxA104. There are 5 models: ATLS100MA104, ATLS250MA104, ATLS500MA104, ATLS1A104 and ATLS1.5A104.

The ATLSxA104 series is an electronic module designed for driving diode lasers. The ATLSxA104 series laser drivers have ultra low output noise, compact size, and two kinds of packaging are available: DIP and SMT. It is only a metal enclosure with a volume of 20.14 × 14.6 × 8 (mm), which not only saves valuable PCB space, but also prevents interference with other surrounding electronic devices. The output current of the ATLSxA104 can be linearly set by the input voltage and can also be modulated by external signals up to 4.67MHz. The driver has temperature compensation network so that the output current stays the same even as the controller temperature increases.

Here is an internal block diagram of ATLSxA104:

The internal block diagram shows that the laser driver provides these the functions: Laser current set,laser current limit, laser current monitoring, loop good indication, over temperature protection, soft start, standby, and shut down. Please check the application notes for more information on these features:

We have specially designed the evaluation board for evaluating the laser driver better. It’s very convenient that the laser driver ATLSxA104 collocates with the evaluation board ATLS1A103DEV1.0.
