DESCRIPTION
The MS5607-02BA is a new generation of high resolution altimeter sensors from MEAS Switzerland with SPI
and I2C bus interface. This barometric pressure sensor is optimized for altimeters and variometers with an
altitude r esol uti on of 20 c m. The sensor m odule i nclud es a hig h line ar ity pressure s ens or and a n ul tr a l o w power
24 bit ΔΣ 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 MS5607-02BA can be interfaced to virtually
any micr oc ontroller. The comm unic ation prot oc ol is s i mple, without the need of pr ogr am ming internal regi sters 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.
