Module de pression* barométrique de précision MS5611        Bild 24bit-Sensor


Bloc diagram

The MS5611 is a high precision pressure sensor module and includes a linear pressure measurement element (pressure die) and an ultra low power 24 bit ΣΔ- A/D-converter with internal factory calibrated coefficients. The main function is to convert the uncompensated analogue voltage from the pressure die to a 24bit digital value, as well as providing a 24 bit value for the temperature. These values can be calculated with the aid of the internal coefficients in any external processor to the real calibrated values. The MS5611 provides different operations modes that allow optimizing for speed and current consumption. A consumption of 0.9μA at one conversion per second (8bit) to 12.5μA (24bit) and resolution selection per conversion enables an optimum application specific power performance trade-offs to be realized.

The modules communicate via a four-wire SPI or two-wire I²C interface. The MS5611 is mounted in a small QFN-package and allows the integration in miniaturized mobile devices without any additional components. The sensing principle employed leads to very low hysteresis and high stability of both pressure and temperature signal.

*Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.
