PCN: LDD-1303 Hardware Update v1.40


We hereby inform you that we have made a hardware update to our Laser Diode Driver LDD-1303 (0-20 A / 1-120 V).

The new hardware version 1.40 is delivered as standard with immediate effect.


Hardware change

The powerstage inductors were changed to increase mechanical robustness of the device. The electrical characteristics are not affected.

The new hardware version is 100% software compatible with the previous version of the LDD-1303 and serves as a 1:1 replacement for older versions. We expect that you will not notice any difference compared to the current hardware version.

For more information on the hardware update, please refer to the document LDD-1303 Hardware Release Notes (PDF) or to the LDD-1303 Laser Diode Driver Datasheet (PDF).

If you have any questions, please contact us. We will be happy to help you!

Best regards,
Your Meerstetter Engineering Team
