1.5V LM94021 and LM94022 are Operational from -50 Degrees C to 150 Degrees C
"National's pioneering thermal management innovations set the standard for temperature accuracy, performance over temperature and packaging," said Andrew Jue, director of product marketing for National Semiconductor's Data Conversion Division. "The LM94021 and LM94022 continue this level of innovation and offer our customers a more efficient way to manage thermal performance."
About the LM94021 and LM94022
The LM94021 and LM94022 are precision analog-output CMOS temperature sensors that operate from a supply voltage between 1.5V and 5.5V. They deliver an output voltage that is inversely proportional to measured temperature, for higher sensitivity at elevated temperatures. Users can select one of four programmable gain options: -5.5 mV per degrees C, -8.2 mV per degrees C, -10.9 mV per degrees C or -13.6 mV per degrees C. The LM94021 and LM94022 feature low quiescent currents of 9 uA and 5.4 uA, respectively. These sensors come in the extremely small SC70 package and are footprint-compatible with National's industry-standard LM20 temperature sensor.
Pricing and Availability
The LM94021 and LM94022 are priced at 40 cents each in 1,000-unit quantities. More information is available at http://www.national.com/pf/LM/LM94021.html and http://www.national.com/pf/LM/LM94022.html .
