Miniature Pressure Transducer


Type/Configuration: differential.
Output: digital I2C (< 19 bit).
Package: SMD

Pressure transducer HPSD 8100 is a pressure and temperature sensing device specially developed for low-power apps with ultra-low-pressure ranges and demanding space constrictions. High performance and accuracy combined with a special digital signal interface including 24 bit ΔΣ ADC enables use of this transducer in many pressure measurement applications. Calibration coefficients are stored into internal EEPROM for signal calculation which is then performed using external microcontroller through I2C or SPI interface. Standard 2nd order temperature and pressure compensation provides 0,75% FS total error over 0°C to 70°C temperature range. Low power supply voltage (1.71V to 5.5V), customized compensated temperature range, standard I2C interface and extremely low power consumption provides OEM users maximum freedom for any type of application with dry air or non-corrosive gases or liquids.

Family HPSD 8100 provides easy integration using small, reflow mountable SMD package with footprint pads on short edges leaving enough room for easier routing for the end application. Pressure ports with their flexibility in different options can accept standard pneumatic tubes or can be customized. Different pressure ranges are available for this group starting from 1 mbar up to 10 bar.
