LM94021 Multi-Gain Analog Temperature Sensor
LM94021 Multi-Gain Analog Temperature Sensor
General Description
The LM94021 is a precision analog output CMOS integrated-circuit 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 porportional to measured temperature. The LM94021’s low supply current makes it ideal for battery-powered systems as well as general temperature sensing applications. Two logic inputs, Gain Select 1 (GS1) and Gain Select 0 (GS0), select the gain of the temperature-to-voltage output transfer function. Four slopes are selectable: −5.5 mV/˚C, −8.2 mV/˚C, −10.9 mV/˚C, and −13.6 mV/˚C.
