SMT160 Datasheet, PDF (3/9 Pages) List of Unclassifed Manufacturers – Temperature sensor with digital output

Product highlights
1.
The SMART TEMPERATURE SENSOR represents a significant totally new
development in transducer technology. Its new on-chip interface responds to the
progressively stringent demands of both the consumer and industrial electronics
sectors for a temperature sensor directly connectable to microprocessor input and
thus capable of direct and reliable communication with microprocessors.
2
The SMART TEMPERATURE SENSOR features a duty-cycle modulated square
waveoutput voltage with linear response to temperatures in the -45 °C to +130 °C
range to an accuracy of better than 1.2 °C. In the range from -30 to +100 °C the
linearity is better than 0.2 °C. (TO18)
3.
The SMART TEMPERATURE SENSOR is calibrated during test and burn-in of
the chip. The integral modulator ensures that the sensor unit can communicate
effectively with low-cost processors without the need of (onboard) A-D convertors.
4
The SMART TEMPERATURE SENSOR combines digital output and on-chip
calibration to ensure major cost reductions and performance-related advantages.
5.
Direct connection of the sensor output to the microprocessor input reduces the
number of components and terminals to a minimum, cutting costs and boosting
reliability.
6.
In applications where more sensors are used, easy multiplexing can be obtained by
using more micro processor inputs or by using simple and cheap digital
multiplexers.
7.
Since the sensor requires no subsequent calibration, optimal cost savings are
recorded both during manufacturing and in the course of after-sales servicing.
