Overview
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.
D1 is th...
