TSD305-1C55 TE Connectivity

TSD305-1C55 DIGITAL TEMPERATURE SENSOR Product Description The TSD is a contactless temperature measurement system located in a TO5 package. The TSD includes an infrared sensor (thermopile) and a sensor signal conditioner. 2 The TSD can be interfaced to any microcontroller by an I C interface. This microcontroller has to calculate the temperature results based on the ADC values and the calibration parameters Features 0C +100C measurement range Small size Up to 1C accuracy 2 I C Interface Low current consumption Operating Temperature Range: -10C +85C Applications Contactless temperature measurement Climate control Industrial process control Household applications SENSOR SOLUTIONS /// DATASHEET TSD305-1C55 10/2016 Page 1 TSD305-1C55 Digital Thermopile Sensor ABSOLUTE MAXIMUM RATINGS Absolute maximum ratings are limiting values of permitted operation and should never be exceeded under the worst possible conditions either initially or consequently. If exceeded by even the smallest amount, instantaneous catastrophic failure can occur. Even if the device continues to operate satisfactorily, its life may be considerably shortened.
