  • Page 3 How to use the Manual Remark: Please read all instructions before powering up the device. Please see section “Power Dissipation” for more details about thermal power losses during operation. Please pay attention to all safety warnings. If you have any doubt or suggestion, please do not hesitate to contact us! Absolute maximum Ratings (destroying limits) All input pins may not exceed the voltage range below zero (GND) and beyond VCC, resp.
  • Page 5 How to get started The basic settings (scaling and BIAS current etc.) can be adjusted by potentiometer. Bias set a dc output current up to 1.6 A without connecting input signal. You need an additional waveform generator which has to be connected to the input terminal.
  • Page 6 Required Laser Diode Pinout The LDP-VRM 045-12 CA is designed for a direct connection to almost all kinds of laser diodes. Be careful to consider the polarity of the laser diode and connect it correctly to the driver. Power Driver Block Diagram...
  • Page 7 Input (#1) The analog setpoint signal is provided via connector #1 on pin 3. The output current follows the input signal proportionally within the driver’s limitations (bandwidth, max. current, rise time). Jumper (#2) The analog input can be switched to an inverted digital input. Set the jumper left to activate the inverted digital input.
