DESCRIPTION
The MS5607-B is a new generation of high resolution altimeter sensors from MEAS Switzerland with SPI and
I2C bus interface. It is optimized for altimeters and variometers with an altitude resolution of 20 cm. The sensor
module includes a high linearity pressure sensor and an ultra low power 24 bit ?Σ ADC with internal factory
calibrated coefficients. It provides a precise digital 24 bit pressure and temperature value and different operation
modes that allow the user to optimize for conversion speed and current consumption. A high resolution
temperature output allows the implementation of an altimeter/thermometer function without any additional
sensor. The MS5607-B can be interfaced to virtually any microcontroller. The communication protocol is simple,
without the need of programming internal registers in the device. Small dimensions of only 5.0 mm x 3.0 mm
and a height of only 1.0 mm allow for integration in mobile devices. This new sensor module generation is based
on leading MEMS technology and latest benefits from MEAS Switzerland proven experience and know-how in
high volume manufacturing of altimeter modules, which have been widely used for over a decade. The sensing
principle employed leads to very low hysteresis and high stability of both pressure and temperature signal.
