AQCL200MA410DF is a quantum cascade laser driver with differential analog input control.It is different from AQCL500MA410SE, another QCL driver with single ended input control. The AQCL500MA410DF is a chassis mount electronic module designed for driving QCLs. It delivers ultra-low noise current and still preserves a wide modulation bandwidth.The AQCL500MA410DF comes with
protections for over-voltage, under-voltage, over current, and over temperature.To monitor the working status of the laser driver, there is a control loop good indication pin, LPGD; and the output current monitor pin, LIO.
