Analog Technologies, Inc is a company specialized in laser and TEC technology. Therefore, there are various kinds of laser drivers for customers to choose. Based on the power input type, ATI’s laser drivers are divided into AC input modules and DC input modules. For the DC input modules, we have both linear type and switch type. Today, I will introduce one high voltage constant current laser driver, whose part No. is ATLS8A216, which is the most popular among customers.

Now, please take a look at its physical photo below:

For its main parameters, it can be concluded as the following: Power Supply Voltage VPS Range is from 5.5V to 15V; Full Swing Output Voltage is from 0.8V to 0.8VPS (input voltage); Maximum Output Current is 8A; its High Efficiency can achieve ≥90%; Both DIP and SMT Packages are available; Compact Size is 27.4×21×5.7 (mm).

This high voltage laser driver has two current set ports digitally controlled to switch between them for setting the output current. This feature allows modulating the laser digitally with 2 preset current values. The laser driver has 3 states: Operation, Standby and Shutdown. Under Standby mode, all the laser driver components works except the output stage.
