The ATLS250MA106 is an electronic module designed for driving diode lasers with up to 250mA extra low noise current. The output voltage is 1.5V to 4V when powered by a 5V power supply. The output current of the ATLS250MA106 can be set by an input voltage linearly or modulated by an external signal of up to 100 KHz in bandwidth, resulting in a minimum 1.5μS rise and fall times at the output current.
