Drive laser diodes with low noise, including DPSSL, EDFA, fiber laser, direct diode lasers, etc.


This laser driver is an electronic module designed for driving diode lasers with up to 2A constant current, highefficiency, low noise, high reliability, zero EMI, and small package.

It provides these functions: laser constant current control,laser current monitoring, over current and thermal protection,laser current control indication, laser diode status indication, soft start, and shut down.

It comes with a high stability low noise 2.5V voltagereference output which can be used for setting the outputcurrent. The reference output can also be used for the ADCs (Analog to Digital Converters) and/or DACs (Digital toAnalog Converters).
