How much do you know about laser diode and laser drivers? Today let me have a full guide for you on ATI’s laser drivers. The product I am going to say something about is one High Efficiency AC Input Laser Driver, whose part number is AAS45A4V2. Then you may ask, what does the 45A represent? 45A is the maximum output current. Now you must be surprised at the technology we have achieved. Now, let us know something more about its other parameters. This High Efficiency AC Input Laser Driver’s efficiency can be over 76%; wide output voltage ranges from 0 to 4V; high speed digital modulation can be 5kHz. Please take a look at the physical photo of this laser driver.
The AAS45A4V2 laser driver comes with a high stability low noise 2.5V reference voltage. It can be used for setting the output current and maximum output voltage. This reference can also be used as the voltage reference for external ADCs (Analog to Digital Converters) and DACs (Digital to Analog Converters), which can be used for monitoring and/or setting the laser current and maximum output voltage, the so-called compliance voltage.
There is much more information about this product, for details, please refers to our datasheet.
