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 resolution of 20 cm. The sensor module includes a high linearity pressure sensor and an ultra low 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 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.
