Air temperature sensor TSYS01 series

for the aerospace industry

TSYS01-FAMILY Digital Temperature Sensors Specifications  High Accuracy Temperature Sensor  TSYS01: ±0.1°C @ Temp.: -5°C … +50°C  TSYS01-1: ±0.1°C @ Temp.: -20°C … +70°C  16/24 bit Resolution  Low Power  SPI/I2C Interface  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. Features Applications  High Accuracy  TSYS01: ±0.1°C @ Temp.: -5°C … +50°C  TSYS01-1: ±0.1°C @ Temp.: -20°C … +70°C  Adjustment of high accuracy temp. range on request  Low Current, <12.5 μA (standby < 0.14 μA)  SPI / I2C Interface  Small Package: QFN16  Operating Temperature Range: -40°C … +125°C  Industrial Control  Replacement of Thermistors and NTCs  Heating / Cooling Systems  HVAC
