TSYS03 Digital Temperature Sensor Product Description The TSYS3 is a miniature digital temperature sensor that provides factory calibrated highly accurate temperature data. The device contains a durable temperature sensor element, A/D converter, and microcontroller to manage data communications 2 via an I C interface. TSYS3 is available in a TDFN8 or a XDFN6 package to easily adapt to the space available on a PC board. These packages are very small and have low thermal mass which provides a quick response to temperature changes. The operating and measurement temperature range is -40 to Features +125C with a resolution of 0.01C. High Accuracy 0.5C Temp.: 0C +60C Operating and sleep currents are extremely low making this Adjustment of high accuracy temperature range sensor ideal for mobile and battery power applications. on request Low Supply Current < 5 A (standby < 0.4 A) 2 I C Interface up to 1MHz Small IC-Package TDFN8 2.5mm x 2.5mm and XDFN6 1.5mm X 1.5mm Operating Temperature Range: -40C +125C Programmable I2C Address Applications Industrial Control Replacement of Precision RTDs, Thermistors and NTCs Heating / Cooling Systems HVAC Medical probes and patient monitoring Weather Stations Fitness watches and wearables Consumer appliances SENSOR SOLUTIONS /// DATASHEET TSYS03 07/2020 Page 1 TSY S0 3 Digital Temperature 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. And even if the device continues to operate satisfactorily, its life may be considerably shortened.
