ATLS1A101 - Low Noise Constant Current Laser Driver

General Description

The ATLS1A101 is an electronic module designed for driving diode lasers with low noise current of up to 1A.

The ATLS1A101 can be modulated by an external signal.

There are two modulation ports for the input signal, one for high speed modulation and the other for low speed.

Analog Technologies FEATURES Ultra Low Noise: <6µA* High Output Current: 1A High Absolute Accuracy: <0.1% Low Noise Constant Current Laser Driver ATLS1A101 Figure 1 is the actual size top view of the ATLS1A101, which shows the pin names and locations. APPLICATIONS Figure 2 shows a stand-alone application circuit, where W1 sets the current limit and the output current at the same time. It is recommended that the current limit is set to 1.1 times of the output current. S1 is the shut down switch. The internal equivalent input circuit of SDN pin is a pull-up resistor of 100K being connected to VPS. If choose not to use a switch (S1) to control the laser, leave the SDN pin unconnected.
