Chapter 3 Description
The LD2000R is a low-noise, stable laser diode current source that can be
operated with laser diodes having a common laser anode and monitor photodiode
cathode. The driver operates in an automatic power control (APC) mode using the
built-in monitor photodiode integrated in the laser diode for feedback or a constant
current (CC) mode. On board trimpots are provided for controlling the laser power
and current limit. Both functions can also be controlled via an external voltage
source. The LD2000R supports a wide range of laser diodes with drive currents up
to 100 mA and photodiode currents from 20 µA to 2 mA. The LD2000R also has
an external modulation input to support applications that require modulating the
laser output.

NOTE
The Laser Diode case must remain floating with respect to both the power
supply ground, and the chassis ground.
NOTE
Read the section on Operating Modes (page 11) before attempting to operate
the LD2000R.
WARNING
The LD2000R uses CMOS circuitry to minimize power drain. Use anti-static
precautions while handling the LD2000R to prevent permanently damaging
the device.
