SMTAS04USB mini – Evaluation board for SMT172 Introduction
This document describes a 4 channel temperature measurement system: The New Smart Temperature Acquisition System (SMTAS04usbmini). It is based on the use of the Smartec temperature sensors SMT172. The SMT172 is a three terminal integrated temperature sensor with a duty cycle output. Two terminals are used for the power supply of and the third terminal carries the output signal. The output signal of the sensor is a duty-cycle-modulated square-wave signal (see Figure 1).

Temperature Sensor SMT172 Regularly Smartec is asked for a temperature sensor with an I2C output. Because of the low power consumption of the SMT172 sensor itself, the self heating of the sensor is negligible, which contributes to its precision. An on chip integrated I2C ...
