Temperature Sensors

A temperature sensor detects the temperature of an object or of its environment and converts the reading into an electrical signal. Common types of temperature sensors include thermocouples, resistance temperature detectors (RTDs), thermistors, local temp sensor ICs, and remote thermal diode temperature sensor ICs. Thermocouples, RTDs, and thermistors are sensing elements with electrical properties that vary predictably with temperature. Local temperature sensor ICs utilize the physical properties of transistors on the die as the sensing element. Clinical grade temp sensors meet the clinical thermometry specification of the ASTM E1112 for accuracy. Remote thermal diode temperature sensors employ an external bipolar transistor as the sensing element and include all the signal conditioning circuitry necessary to measure temperature using one or more external transistors.

Our wide selection of silicon-based temperature sensor ICs support a variety of applications including medical, industrial, data center, and mobile. In addition to temperature sensors, we offer fan controllers and themostat ICs. Our fan controller ICs monitor and control fan speeds in system cooling applications. Our thermostat ICs measure temperature and provide a power switch output for temperature-based monitoring and control applications. Additional industry-leading features include:

  • Temp sensors with accuracy up to ±0.5℃
  • Fan controllers with temp sensing, voltage monitoring and GPIO
  • Remote temperature sensors with up to 7 channels
  • Clinical grade temperature sensor with ±0.1°C accuracy
