A high stability low noise 2.5V reference voltage is provided internally for setting the output current. This reference can also be used as the voltage reference for external ADCs (Analog to Digital Converters) and/or DACs (Digital to Analog Converters) .

The ATLS1A103 is an electronic module designede for driving diode lasers with up to 1A low noise current. The output voltage is 1.5V to 4V when powered by a 5V power supply. It uses two drivers,one is switch mode and the other is linear mode .The former results results in high power efficiency ,the latter keeps the output noise low and allows high modulation speed.
