The output current of the ATLS100MA104 can be set by an input voltage linearly or modulated by an external signal of up to 4.6MHz in bandwidth, resulting in a minimum 75nS rise and fall times at the output current. 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.
A: For laser drivers ATLSXA201 and ATLSXA202, LIS pin should be toggled between these 2 voltages: a high value corresponding to the operation current and a low value corresponding to half of the threshold current of the laser the driver is driving.
