The SK657 Gavarnie Laser Diode Current Controller is a low-noise programmable current source for operating lasers whose anode terminal is grounded or floating from ground. While the laser biasing current is controlled using two paralleled current sources for a fine adjustment between 0 and 500 mA, two inputs are provided for DC- and RF-modulation. Several interfaces are available to connect the laser diode in order to facilitate the integration of the SK657. Usual functionalities for a safe operation are also provided : slow turn-on, interlock, compliance over-voltage detection, current limitation… Acting as true independent current sources, several SK657 modules can thus operate in parallel to increase the output current while maintaining ultra-low noise operation. Due to its unique specifications, the SK657 is the right choice for most demanding applications.
