The ATLS201D is a series of high efficiency electronic modules designed for driving diode lasers with low noise constant current. It has high reliability, zero EMI (Electro-
Magnetic Interference), and is packed in small DIP package.The series includes ATLS2A201D,ATLS3A201D ATLS4A201D, and ATLS6A201D. The output voltage range is from 0V to 4V when powered by a 5V power supply. The evaluation board introduced by this application
note, ATLS201DEV1.0, is designed for evaluating these laser driver modules conveniently.
The evaluation board has a dummy laser formed by a series of regular laser diodes and can be used to emulate how the real laser diode would be driven by the laser driver. The output current and the output current limit can be programmed respectively by the potentiometers mounted on the board. This laser driver evaluation board is of 100 % lead (Pb)-free and RoHS compliant.
