TSYS02 Digital Temperature Sensor

The TSYS02 Series is a single chip temperature sensor. It provides factory calibrated data corresponding to the measured temperature.

3 models are available:

  • The TSYS02P provides a PWM output. Resolution is 0.01°C.
  • The TSYS02S provides a SDM output. The SDM signal is a pulse sequence that may be converted into an analog voltage by a discrete low pass filter. Resolution is less than 0.1°C.
  • The TSYS02D provides an I2C interface. Resolution is 0.01°C.

The temperature range for all models is -40°C to +125°C.


  • High accuracy of ±0.2°C from -5°C to +50°C
  • Adjustment of high accuracy temperature range upon request
  • Wide temperature range of -40°C to +125°C
  • Very small size, TDFN8 package, 2.5 mm X 2.5 mm
  • Low supply current less than 420 µA (standby less than 0.14 µA)
  • 16 bit resolution


  • Industrial control
  • Replacement of precision RTD's, Thermistors and NTC's
  • Heating & cooling systems
  • HVAC
