Fully calibrated TSYS01 replaces thermistors and NTCs

Measurement Specialties now offers the highly accurate TSYS01 digital temperature sensor that integrates a sensing chip and 24-bit analog-to-digital converter (ADC) into one component.

Drawing less than 12.5 μA in a compact QFN16 surface mount package, the fully-calibrated TSYS01 is easily incorporated into a variety of industrial control, HVAC/R and heating/cooling systems.

The 4 mm×4 mm sensor features a wide operating range of −40°C to +125°C, making it a competitively-priced replacement for thermistors and NTCs (negative temperature coefficients).

Delivering reliable, precise operation, the TSYS01 is factory-calibrated to provide an exceptionally high accuracy of ±0.1°C as well as high measurement resolution. Custom calibration is also available to meet specific application needs.

The selectable digital output of either I²C or serial peripheral interface (SPI) enables this versatile temperature sensor to interface with a microcontroller that calculates temperature based on the ADC values and calibration parameters.
