GENERAL DESCRIPTION

The advanced and reliable circuitry of the HTC Series achieves 0.0009°C temperature stability. Its small, low profile 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 simplifies use with resistive temperature sensors. The independently adjustable Proportional Gain (P) and Integrator Time Constant (I) can be modified to optimize temperature overshoot and stability.

Other features offer added flexibility. A single resistor sets the maximum output current to your load. 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.
