Semiconductor & IC Thermometer
Device Vendors

Semiconductor thermometers are usually produced in the form of ICs, Integrated Circuits. There are many types, sizes and models. Most are quite small and their fundamental design results from the fact that semiconductor diodes have voltage-current characteristics that are temperature sensitive.

That means that semiconductor triodes or transistors are also temperature sensitive. Needless to say, there devices have temperature measurement ranges that are small compared to thermocouples and RTDs, but, they can be quite accurate (e.g. ± 0.5°C or so) and inexpensive and very easy to interface with other electronics for display and control.

Listed below are links to some of the makers and suppliers of semiconductor thermometer devices

Thanks for visiting. 

  • AdSem, Inc..
    Supplier of novel Si and Ge NTC thermistors with unique performance: the highest operating temperature, the widest interchangeability temperature range, the highest thermosensitivity, the smallest size and universal R-T dependence. AdSem, Inc. is only company in the world that offers semiconductor temperature sensors that function as Negative Temperature Coefficient thermistors rather than diodes. They also offer the smallest semiconductor RF and low-temperaturre IR bolometers.

  • Analog Devices.
    One of the giants in specialized IC devices is also one of the leaders in innovative IC temperature sensor packages and a-to-d converters.

  • Maxim Integrated Circuit Devices
    One of the most innovative (in terms of sensors) with temperature sensors, micro-sized temperature dataloggers, humidity sensors, sensor kits for low cost exploration of packaging and implementation of new sensor/logger designs-like a miniature weather station.

  • MicRed
    THERMOSENS Family of CMOS compatible, process independent temperature sensors with either analog or digital output.

  • National Semiconductors
    Yes, that National Semiconductors, one of the largest of integrated circuit makers for standard ic op-amps, a-to-d converters, counters, timers and then a whole passle of digital devices

  • Sensirion
    Develops and markets CMOS sensors for temperature measurement, differential pressure, humidity, mass, air and gas flow

  • Thermochron
    Their web site is dedicated to the iButton temperature sensor & data logger featured as the product of the month for January 2002 on this web site.

  • TPI Corporation
    A manufacturer of digital temperature and pressure sensors that connect directly to digital I/O ports and micro-PLC's.
