The SMT172 is a three terminal integrated temperature sensor, with a duty-cycle output.

Two terminals are used for the power supply of 2.7 -5.5 Volts and the third terminal carries the output signal. A duty cycle modulated output is used because this output is interpretable by a microprocessor, while the analogue information is still available.

The sensors are available in a number of encapsulations: TO18, TO92, TO220, SOIC-8L, SOT223, HEC and in a 7 mm ss. probe with 5 mtr cable. SMT172 can be supplied as a naked die as well. For quick design-in a lot of applications are available on the web and for plug and play we have designed a Smart Temperature Acquisition System for 4 or 8 Smartec Temperature Sensors. It was designed to get the best possible temperature measurement results with the SMT172 temperature sensors (absolute accuracy 0.1 °C, noise <0.0001 °C), at low cost. We offer you an application to connect the board to an Excel  application. In this way a low budget high accurate measurement system can be built.

The SMT172 has an overall accuracy of 0.1 °C in the range from -20 °C to +60 °C and an accuracy of 0.4 °C from -45 to +130 °C. This makes the sensor especially useful in all applications where "human" (climate control, food processing etc.) conditions are to be controlled.

The CMOS output of the sensor can handle cable lengths up to 20 meters. This makes the SMT172 very useful in remote sensing and control applications.
