APPLICATIONS
Ideal for integrated laser driver or LED packages that include
temperature control, often utilized in medical diagnostic
equipment, remote sensing, analytical instrumentation,
military, and communications applications.
POWER YOUR APPLICATION WITH
THE RIGHT FEATURES
The WTC32ND will control temperature using thermistors,
RTDs, or linear temperature sensors such as the LM335
or the AD590. Adjust temperature using the onboard
trimpot or a remote voltage input from a panel mount
potentiometer, DAC, or other voltage source. A default
temperature setpoint configuration provides fault tolerance
and avoids accidental damage to system components.
Adjustable trimpots configure heat and cool current limits.
The WLD33ND Laser Driver maintains precision laser
diode curent (Constant Current Mode) or stable photodiode
current (Constant Power mode) using electronics
compatible with A/B Type lasers.
