SMT172 Temperature Sensor Introduction The SMT172 is an ultra-low power, high-precision temperature sensor that combines the ease of use with the worlds leading performance over a wide temperature range. Using the most recent advances in the silicon temperature sensing technology, the SMT172 has applied some really sophisticated IC design techniques as well as high-precision calibration methods, to achieve an absolute inaccuracy of less than ± 0.1°C in the range of -20°C to 60°C The SMT172 operates with a supply voltage from 2.7V to 5.5V. The typical active current of only 60µA, the high speed conversion over 4000 outputs per second (at room temperature) and an extremely low noise makes this sensor the most energy efficient temperature sensor in the world (0.36µJ/measurement). 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. The SMT172 can be supplied as a naked die as well. 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 conditions (climate control, food processing etc.) are to be controlled.
