DESCRIPTION

This laser driver is an electronic module designed for

driving diode lasers with up to 1A constant current, high

efficiency, low noise, high reliability, zero EMI, and small

package. Figure 1 shows the photo of an actual

ATLS1A201D.

It provides these the functions: laser constant current control,

laser current monitoring, over current and thermal protection,

laser current control indication, laser diode status indication,

soft start, and shut down.

It comes with a high stability low noise 2.5V voltage

reference output which can be used for setting the output

current. The reference output can also be used for the ADCs

(Analog to Digital Converters) and/or DACs (Digital to

Analog Converters).
