TSYS01 Digital Temperature Sensor

Measurement Specialties, Inc. (NASDAQ: MEAS) Model TSYS01 digital temperature sensor encapsulates a temperature sensing chip and a 24-bit ADC in a QFN16 package. This new technology provides on-board factory calibration coefficients that provide highly accurate temperature information accompanied by high measurement resolution. For improved performance specific to the application, custom calibration is available upon request.  Integration with microcontrollers is achieved through an I2C or SPI interface.

This digital temperature sensor is specifically designed for industrial control, HVACR and heating/cooling systems. Optimal performance is achieved through the use of a stabilized, noise-free power supply with the placement of a ceramic capacitor close to the supply pins, and keeping supply lines as short as possible.

The TSYS01 is easily embedded in most electronic applications as it draws < 12.5µA during normal operations and < 0.14µA on standby. Its broad operating range (-40ºC to +125ºC), small package and high accuracy (±0.1ºC) makes it an ideal replacement for Thermistors and NTCs. Furthermore, it can be mated to an external element should that prove most cost-effective. For best results, customers should proceed according to IPC/JEDEC J-STD-020D (Pb-Free Process) when using solder reflow process.
