The TSYS01 is a single device, versatile, new
technology temperature sensor. The TSYS01 provides
factory calibrated temperature information. It includes a
temperature sensing chip and a 24-bit ΔΣ-ADC. The
essence of the digital 24-bit temperature value and the
internal 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 operating 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.
