400mA Laser Diode Driver for Type A & B laser diodes with a photodiode range of 5-125 µA - LDD400-3

The advanced and reliable circuitry of the HTC series achieves 0.0009°C temperature stability. Its small, low profi le package is ideal for designs with space constraints. The linear, PI control loop offers maximum stability while the bipolar current source has been designed for higher efficiency.The HTC temperature controllers are easily configured for any design. Virtually any type of temperature sensor can be used with the HTC and a built in sensor bias current source simplifi es use with resistive temperature sensors. The independently adjustable Proportional Gain (P) and Integrator Time Constant (I) can be modifi ed to optimize temperature overshoot and stability.Other features offer added flexibility. A single resistor sets the maximum output current to your load. Add a diode to operate resistive heaters with a unipolar output current. An onboard reference voltage simplifies potentiometer control of the temperature setpoint. You can also choose to operate remotely with an external setpoint voltage. Two monitor pins provide access to the temperature setpoint voltage and the actual sensor voltage. Key Features Compact Size - 1.5 and 3.0 A Models Interfaces with Thermistors, IC Sensors, & RTDs Single supply operation +5 V to +12 VDC (contact factory for higher voltage operation) +11 V compliance with +12 V input Stabilities as low as 0.0009°C Temperature Setpoint, Output Current Limit, Sensor Bias, Proportional Gain, and Integrator Time Constant are User Adjustable Monitor outputs for Temperature Setpoint and Actual Temperature Linear Bipolar or Unipolar Output operates thermoelectrics or resistive heaters
