TSYS01-FAMILY Digital Temperature Sensors Specifications High Accuracy Temperature Sensor TSYS01: 0.1C Temp.: -5C +50C TSYS01-1: 0.1C Temp.: -20C +70C 16/24 bit Resolution Low Power SPI/I2C Interface QFN16 Package Features High Accuracy The TSYS01 is a single device, versatile, new TSYS01: 0.1C Temp.: -5C +50C technology temperature sensor. The TSYS01 provides TSYS01-1: 0.1C Temp.: -20C +70C factory calibrated temperature information. It includes a Adjustment of high accuracy temp. range on request temperature sensing chip and a 24-bit -ADC. The essence of the digital 24-bit temperature value and the Low Current, <12.5 A (standby < 0.14 A) internal calibration values lead to highly accurate SPI / I2C Interface temperature information accompanied by high Small Package: QFN16 measurement resolution. Operating Temperature Range: -40C +125C 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: Applications Converting temperature into digital 16/24 bit ADC value Industrial Control Providing calibration coefficients Replacement of Thermistors and NTCs Providing ADC value and calibration coefficients by SPI or I2C Heating / Cooling Systems interface.

If exceeded by even the smallest amount, instantaneous catastrophic failure can occur. And even if the device continues to operate satisfactorily, its life may be considerably shortened.
