TSD305-1SL10 TE Connectivity

TSD305 DIGITAL TEMPERATURE SENSORS Product Description The TSD Series are digital thermopile sensors in a TO5 package. The TSD sensors include an infrared sensor (thermopile) and a sensor signal conditioner. 2 The TSD sensors 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 up to +300C measurement ranges Small size Small field of view available 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 SERIES 05/2020 Page 1 TSD305 SERIES 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.
