Product Announcement from Texas Instruments High-Performance Analog
The LMT84 is a precision analog output CMOS integrated-circuit temperature sensor that operates at a supply voltage as low as 1.5 Volts. A class-AB output structure gives the LMT84 strong output source and sink current capability for driving heavy loads. This means it is well suited to source the input of a sample-and-hold analog-to-digital converter with its transient load requirements. While operating over the wide temperature range of −50°C to 150°C, the LMT84 delivers an output voltage that is inversely proportional to measured temperature. The LMT84 low supply current makes it ideal for battery-powered systems as well as general temperature sensing applications.
The LMT84 can operate with a 1.5V supply while measuring temperature over the full −50°C to 150°C operating range.
The LMT84 is a cost-competitive alternative to thermistors.
