QFN16 Package
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.
