Product information "400mA Laser Diode Driver for Type A & B laser diodes with a photodiode range of 5-125 µA - LDD400-3"
The LDD P Series of laser diode drivers come in three compact models to work with all laser diode / photodiode configurations. Each model is available in 200 mA and 400 mA versions to best fit your laser diode requirements. When it is essential to have high performance in your application, these low noise drivers offer excellent current stability in constant current mode or power stability in constant power mode. Precisely control the laser diode or photodiode setpoint current with the on-board Output Current Adjust trimpot or via a remote voltage to the modulation input. The modulation input's small signal 3 dB bandwidth is DC to 2 MHz in constant current mode and dependent on photodiode speed in constant power mode.
