DESCRIPTION:

The ATLS250MA104 is an electronic module designed for driving diode lasers with up to 250mA extra low noise current. The output voltage is 0.5V to 3.6V when powered by a 5V power supply. A highly stable 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) which are utilized for converting the analog signals, such as LIO which represents the output current, into digital signals, and/or converting the digital signals into analog ones for setting the analog voltages, such as LIS which sets the output current. The ATLS250MA104 is packaged in a 6 sided metal enclosure, which blocks EMIs (Electro-Magnetic Interferences) to prevent the controller and other electronics from interfering each other.
