TSYS02 Digital temperature sensor



The TSYS02 is a single chip, versatile, new technology temperature sensor. The TSYS02 provides factory calibrated temperature information. It includes a temperature sensing chip, a 24 bit _Σ-ADC and an EEPROM. The essence of the digital 24 bit temperature value and the internal factory set calibration values lead to highly accurate temperature information accompanied by high measurement resolution.

The TSYS02 can be interfaced to any microcontroller by an I²C interface. This microcontroller has to calculate the temperature result based on the ADC values and the calibration parameters.

The basic working principle is:

  • Converting temperature into digital 16 bit ADC value
  • Providing calibration coefficients
  • Providing ADC value and calibration coefficients by I²C interface
  • Calculation of the temperature values

The TSYS02 impresses with its accuracy of 0.2°C, whereby the accuracy and the temperature range can be adjusted on request. Additionally the TSYS02 features a very low current consumption (<18 μA ; Standby < 0.14 μA) and low self heating. Because of ist small size and the supply voltage of 3.3V the temperature sensor is especially suitable for mobile, battery bound applications.
