The ATLSXA214D is a series of high efficiency constant current laser drivers for driving one or multiple laser diode arrays. It has high reliability, zero EMI (Electro-Magnetic Interference), and is packed in small DIP package. The laser driver series includes ATLS4A214D and ATLS6A214D.
The evaluation board introduced by this application note, ATLS214EV1.0, is designed for evaluating these laser drivers conveniently.
It is recommended to read this application note with the ATLS4A214D or ATLS6A214D datasheet which provides more detail information about the specifications and application guidelines for the laser drivers.
This evaluation board is on the 4 edges of the board, it features solder pads for all the interface ports provided by the laser driver. The solder pads can be used by clips or soldered with wires for connecting to external circuits. The power supply input is connected on the upper edge of the board. The incoming wires can be soldered on the pads, or clipped by alligator clips, or use the terminal block and tight the wires by the screws. In the upper middle of the board, there is an LED. When the controller works properly, it will be lit up. On the left side of the controller, there is a terminal block.
