... It operates over a –55°C to 130°C (grade 7) or –40°C to 85°C (grade 9) temperature range. The power supply operating range is 2.4V to 5.5V. The accuracy of the STLM20 is ± 1.5° ambient temperature of 25°C. The temperature error increases linearly and reaches a maximum of ±2.5°C at the temperature range extremes ...

... Transfer function The STLM20’s transfer function can be described in different ways, with varying levels of precision. A simple linear transfer function, with good accuracy near 25°C is expressed as: Equation 1 Over the specified operating temperature range, the best accuracy can be obtained by using the parabolic transfer function: ...
