ATS45C

www.DataSheet4U.com aTS45C LOW-VOLTAGE ULTRA-LOW-POWER TEMPERATURE SENSOR WITH HIGH OUTPUT DRIVE Fully Released Specification General Description The aTS45C is a silicon integrated circuit temperature sensor. The aTS45C maintains an accuracy of ±4°C over a temperature range of −20°C to 100°C. At 25°C (room temperature) the accuracy is calibrated to typically better than ±2°C (VOUT = 250mV). This calibration is done during probe and guaranteed on each device. The aTS45C also maintains one of the lowest power consumption requirement in the industry and therefore reduces any inaccuracies due to selfheating.
