Temperature Sensors

ST’s temperature sensor portfolio includes both analog and digital temperature sensor ICs. Both types are suitable for a wide range of applications including industrial, consumer, portable, medical, home appliances and computer market segments, thanks to their high accuracy and low-power consumption.

The analog temperature sensors feature low power consumption, good linearity, and accuracy as high as ± 0.5 ºC flat across the whole temperature operating range as wide as –55 to +130 °C and up to 200 °C (non-continuous).

The digital temperature sensors feature low power consumption as low as 20 µA with up to 12-bit resolution able to digitize temperatures to a resolution up to 0.0625 °C to ensure high accuracy flat across the whole operating range as wide as –55 to +125 °C.

Additional features include an I2C/SMBus output with selectable addresses (up to 8), energy-saving one-shot temperature reading, a dedicated pin for interrupt or thermostat/comparator function and programmable threshold with hysteresis. Factory-calibrated, our digital sensors do not require any external components to measure temperature.

The STTS series with its onboard delta-sigma analog-to-digital converter (ADC) specifically targets DRAM DIMM modules in servers, desktops, and mobile personal computing platforms including laptops, as well as a variety of industrial applications.

ST’s temperature sensor IC portfolio is available in a wide range of packages ranging from insertion models such as theTO-92 to the smallest one on the market, the 6-lead UDFN package (2 x 2 x 0.5 mm), for use in any environment and equipment.
