Low-current variant of the LDD-1121, with LPC option. Also suited for driving reference LEDs (diode driver). If you are interested in the LPC option, please do not hesitate to contact us.
The LDD-1124 is a specialized Laser diode driver able to work as CW Laser diode driver or Laser diode pulse driver. Core element of the LDD's internal current source is the generation of highly precise 333 ps timing steps that results in 30 μA resolution and very low ripple. Typical applications for the LDD-1124 are RGB light sources and highly accurate reference light sources.
Equipped with optional light measurement circuitry, the LDD-1124-SV-LPC can also be operated as a Laser Power Controller (LPC).
All LDD-1124s offer various safety features, including an input for Laser diode temperature monitoring. They are fully digitally controlled; their firmware is upgradeable to offer various communication options and to meet specific customer requirements.
