The LM94022 is a precision analog output CMOS integratedcircuittemperature sensor that operates at a supply voltageas low as 1.5 Volts. A class-AB output structure gives theLM94022 strong output source and sink current capability fordriving heavy loads. For example, it is well suited to sourcethe input of a sample-and-hold analog-to-digital converterwith its transient load requirements. While operating over thewide temperature range of −50°C to +150°C, the LM94022delivers an output voltage that is inversely porportional tomeasured temperature. The LM94022's low supply currentmakes it ideal for battery-powered systems as well as generaltemperature sensing applications.
