We hereby inform you that we have made a hardware update to our Laser Diode Driver LDD-1321 (0-1.5 A/ 0-14 V).
After depletion of current stock, the new hardware version 1.30 will be delivered starting approximately in April 2026.
Hardware change
The control op-amp has been replaced with another one with similar but not exactly matching characteristics. The behaviour of the control is defined through external components. Change due to the end of life (EOL) of the component by the manufacturer.
The new hardware version is 100% software compatible with the previous version of the LDD-1321 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-1321 Hardware Release Notes (PDF) or to the Laser Diode Driver LDD-1321 Datasheet (PDF).
If you have any questions, please contact us. We will be happy to help you!
Best regards,
Your Meerstetter Engineering Team
