The LM94021 is a precision analog output CMOS integratedcircuit temperature sensor that operates at a supply voltage as low as 1.5V. While operating over the wide temperature range of −50°C to +150°C, the LM94021 delivers an output voltage that is inversely proportional to measured temperature. The LM94021's low supply current makes it ideal for battery-powered systems as well as general temperature sensing applications.
