201 series constant current laser diode drivers are designed and applied for driving diode lasers with a maximum current of 1A, 2A, 3A, 4A and 6A. This laser driver ATLS1A201D comes with up to 1A low noise current. There are two types of ATLS1A201D laser drivers, ATLS1A201D and ATLS1A201D-PD. The difference is that the latter has a pull-down resistor of 55K to the ground in SDN pin.
This laser driver has a compact size and is packaged in a six sided metal case, which blocks outgoing and incoming electro-magnetic interferences. This laser driver provides multiple functions, such as laser current control indication, over current and thermal protection, laser constant current control, laser current monitoring, laser diode status indication, soft start and quick shutdown. There is a high stability low noise 2.5V voltage reference output, which is used for setting the output current. This reference output can also be used for the ADCs or DACs.
