Part 3. Operating the LD2000
3.1. Setup
The LD2000 is packaged as a component which, with minimal external components, can
be integrated into a system to make a complete laser diode driver system. We recommend
using printed circuit board construction to achieve optimum results. The pinouts for the
LD2000 are provided in Figure 1 and described below. The LD2000 can be used with A,
D, or F style diodes. The D and F style diodes will need to be configured like an A style
diode (see page 3 for diagrams). Please note that the EK2000 is not compatible with the
F Pin Style
