PLD10000/PLD12500 LASER DIODE DRIVER
ADD LASER DIODE PROTECTION FOR LONG
CABLES
With a cable longer than two feet, add a Schottky diode
across the laser diode, see
Figure 15.

ADDITIONAL NOISE FILTERING
The PLD drivers provide low-noise current to the laser
diode, but in some cases additional filtering may be
needed. Refer to
Figure 16 for a simple and effective
filter.

MONITOR CALIBRATION CIRCUIT
A small offset may be present when measuring the
P Monitor, I Monitor or LIM I Monitor voltage with respect
to the actual output. Use the circuit shown in
Figure 17 to
remove any offset.

PRODUCT VARIATIONS
We design and manufacture our products in-house, and
that gives us the unique ability to quickly and inexpensively
modify our drivers and controllers to suit your application.
Our Product Variation service allows us to address your
design requests, from prototype quantities to long-term
high-volume manufacturing.
Examples of past Product Variations include:
• Replacing current limit trimpots with fixed-value
resistors to maximize long-term stabilty in an OEM
laser controller system
• Increasing the maximum output current
• Changing the controller input voltage
