TI推出LMT87/LMT87-Q1模拟温度传感器

The LMT87/LMT87-Q1 are precision analog output CMOS integrated-circuit temperature sensors. A class-AB output structure gives the LMT87/LMT87-Q1 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-too-digital converter with its transient load requirements. While operating over the wide temperature range of −50°C to 150°C, the device delivers an output voltage that is inversely proportional to measured temperature. The LMT87/LMT87-Q1 low supply current makes it ideal for battery-powered systems as well as general temperature sensing applications.

The LMT87/LMT87-Q1 can operate with a 2.7 V supply while measuring temperature over the full −50°C to 150°C operating range.

The LMT87/LMT87-Q1 are cost-competitive alternative to thermistors.
