TSYS01 24bit-temperature sensor

The TSYS01 is a single chip, versatile, new technology temperature sensor. The TSYS01 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 TSYS01 can be interfaced to any microcontroller by an I²C or SPI 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 16/24 bit ADC value

• Providing calibration coefficients

• Providing ADC value and calibration coefficients by SPI or I²C interface.

• Calculation of the temperature values
