AQCL3A410DF is a quantum cascade laser driver with differential analog input control. It is different from AQCL3A410SE, another QCL driver with single ended input control. The AQCL3A410DF is a chassis mount electronic module designed for driving QCLs. It delivers ultra-low noise current and still preserves a wide modulation bandwidth. The AQCL3A410DF comes with protections for overvoltage, 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.
