... SMT16030 Version 7/2005 The SMART TEMPERATURE SENSOR is calibrated during test and burn-in of the chip. The integrated modulator ensures the sensor unit can communicate effectively with low-cost microcontrollers without the need of (onboard) A/D converters or an Xtal controlled oscillator. The SMART TEMPERATURE SENSOR combines digital output and on-chip calibration to ensure major cost reductions and performance-related advantages ...

... All not mentioned specifications are the same as for TO18 2 Case connected to ground 3 The SMT 30-160-18 can be used from -65 to +160 °C for a short period without physical damage to the device. The specified accuracy applies only to the rated performance temperature range. 4 Total accuracy includes all errors. ...

... A duty cycle modulated output is used because this output is interpretable by a micro-processor without A-D converter, while the analogue information is still available. The SMT160-30 (TO18 model) has an overall accuracy of 0.7 °C in the range from - +100 °C and an accuracy of 1.2 °C from -45 to +130 °C. This makes the sensor especially useful in all applications where " ...

... With temperatures above 100 °C the accuracy decreases. Non linearity Non-linearity as it applies to the SMT160-30 is the deviation from the best-fit straight line over the whole temperature range. For the temperature range of -30 °C to +100 °C the non- linearity is less than 0.2 °C (TO18). ...

... About noise protection and how to prevent damage caused by a wrong power supply polarity. The Smartec SMT16030 is based on a free running oscillator. Periodic spikes on the power supply line may make the oscillator synchronise, resulting in a false temperature reading. To overcome this problem it is advised to put a filter in the power supply line of the sensor suggested to use a low pass RC filter as given below ...
