Product Overview:

The LDD-1137 is a high voltage, high current laser diode driver able to precisely drive laser diodes in continuous and/or pulsed mode of operation. Designed with the latest generation of eGaN FETs, the LDD-1137 offers faster pulsing performance with improved waveforms and better efficiency compared to the previous available models. A new processing core enables a faster processor connection to the powerful FPGA, more interfaces, more precise timing, additional functions and much more, while still maintaining a 1.5 mA resolution with much higher current and keeping a very low output ripple. The LDD-1137 offers multiple integrated safety features, including an input for laser diode temperature monitoring and current / voltage limits. They are fully digitally controlled; their firmware is upgradeable to offer various communication options and to meet specific customer requirements.
