ORDERING INFORMATION
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.
